Add warning for useless use of sequence

The sequence operator (...) is not really a pure operator for purposes of constant folding, so it's not marked pure, but we're going to carp about using a sequence only for its side effects anyway, since it catches common errors of the form: b286048 | lizmat++ | src/core/ThreadPoolScheduler.pm: Apply delay to all cues, instead of just the first
Spotted by jnthn++
lizmat Files=1155, Tests=53921, 200 wallclock secs (11.26 usr 4.66 sys + 1193.47 cusr 126.92 csys = 1336.31 CPU) 08:39
yoleaux2 14 Dec 2016 21:17Z <jnthn> lizmat: Is it accidental that `$*SCHEDULER.cue: :in(1), :times(2), { say now }` only applies the "in" to the first time? (It's actually setting the delay to 0 after scheduling the first one...)
moritz jnthn: I think if you want delays after the first one, you need to pass in :every(2) 08:40
cue docs.perl6.org/routine/cue :-) 08:41
lizmat jnthn: what moritz said :-)
moritz suddenly feels competent :-) 08:42
lizmat at least, that's always been my interpretation of combining "in" with "times"
moritz though we might want to declare it as :$in, :$every = $in 08:43
lizmat huh? 08:44
that's quite a semantic change
from non-repeating to repeating ??
moritz oh, does :every imply repetition, even if :times isn't set? 08:48
then we shouldn't do that 08:49
lizmat yup
:times is just a limiter on :every, really
jnthn This isn't about :every 09:55
This is about when you *don't* have every and you use time 09:56
*times
My expectation was that :in(2), :times(3) would, in 2 seconds, schedule it 3 times
m: $*SCHEDULER.cue: :in(2), :times(3), { say now }; sleep 4; 09:57

jnthn But notice how two of them are run at 0 seconds, and only one of them at 2 seconds
I'd expect those 3 say statements to spit out a `now` value that is pretty close 09:58
lizmat jnthn: ah, indeed, that's what I would have expected as well 10:01
hmmm...
jnthn Yeah, discovered when I was implementing Test::Scheduler last night for my advent post :) 10:02
lizmat ah, *now* I understand your question 10:05
looks like the $delay=0 is a thinko on my part
looks like the first one scheduled is the last one to execute, because it is the only one that has a $delay 10:06

If it weren't there it'd do what I'd expected, I think :)

ZoffixW Hello. Is there a neat-looking trick for a loop that doesn't react to last/next/redo (and instead passes them further up the food chain)? 14:52
I tried a bunch of stuff with CONTROL {} but I'm either breaking take/warn or getting "MoarVM panic: Trying to unwind over wrong handler" as a sideeffect

.oO( a goto would be handy.... )
 14:56
lizmat
.oO( well volunteered :-)
jnthn ZoffixW: You can't just use labeled loops?
Not aware of a way to skip the handlers though 14:57
ZoffixW Nope.
jnthn I can't see CONTROL helping as the handlers are code-gen'd around the loop 14:58
ZoffixW hm
jnthn So there's nowhere to put a CONTROL that will bypass them
ZoffixW OK. Maybe there's a different way. 14:59
jnthn Could just throw an exception of some kind
ZoffixW m: loop { last without Any }
camelia rakudo-moar b28604: OUTPUT«(timeout)»
ZoffixW That ^ hangs because `without` thunks the `last` and calls `notandthen` which uses a loop of its own to process args. So when it calls that thunk with the `last` the last aborts `notandthen`'s loop and not the original loop 15:00
So somehow I was thinking of making it stop doing that.
lizmat arriving in Cologne& 15:01
jnthn ZoffixW: Hmm
Oh
There is iirc a :nohandler thingy if you use nqp::while
ZoffixW looks into that
jnthn git grep nohandler 15:02
Shows up a bunch of examples
So yeah, there is a way, if you use nqp:: ops :)

rakudo/nom: The statements of `without`/`with` statement modifiers get thunked
rakudo/nom: and fed to `notandthen`/`andthen` infix operators. Those operators
rakudo/nom: use loops to process arguments. So when THOSE loops execute a thunk

MasterDuke jnthn: around for a QAST question? 21:03
or anyone? 21:05
what does p6capturelex do? 21:06
moritz MasterDuke: I don't know, and can only speculate 21:12
MasterDuke well, i'll explain what i'm running into, maybe at this point any other set of eyes will help 21:14
still working on turning -n's "for lines() { $code }" into "while ($_ := get()).DEFINITE { $code }"
i've got it to loop the same number of times as lines in test files, so i assume that part's working 21:15
but i can't ever get the $code to execute
moritz MasterDuke: want to nopaste a patch, or push a branch or something? 21:16
MasterDuke: and maybe a --target=ast dump of small examle code
MasterDuke well, this has some already gist.github.com/MasterDuke17/6e09e...2a0348ef7b 21:17
timotimo p6capturelex is just capturelex with an indirection through the invocation spec of an object
MasterDuke if i take p6capturelex out entirely, -ne '.say' just prints a bunch of (Mu)s 21:18
timotimo "given the specified code object, sets its outer to the current scope"
MasterDuke if i leave it in, -ne '.say' doesn't print anything at all 21:19
if instead i docegen "while ($_ := get()).DEFINITE { say $foobar; $code }", and then do -ne 'BEGIN my $foobar = <something>; .say' i get <something> printed for every line
*codegen 21:20
jnthn This code never actually calls the block
moritz right
jnthn Which is perfect for "for"
moritz it's the equivalent of while ($_ := for()) { &codeobj }
jnthn Since you want to pass it off to map
timotimo ooooh
jnthn $while.push(QAST::Op.new( :op('call'), $body )); # probably does it 21:21
Think I missed that when I last looked at it... :)
moritz or use a different helper function than make_topic_block_ref
jnthn Though even better is to find a way to make it an immediate block
MasterDuke ah, if you reload the gist you'll see a new ast
i added a QAST::Block.new(:blocktype<immediate>), is that what you meant? 21:24
rebuilding now 21:25
moritz MasterDuke: can't you leave out the call to make_topic_block_ref entirely? 21:26
MasterDuke don't know, it was there before
moritz $code is probably already the AST for an immediate block, and make_topic_block_ref turns it into an QAST that returns a code ref 21:27
which is what map wants
but not what :op<while> wants
MasterDuke something didn't work, now trying without make_topic_block_ref 21:28
ah ha! much closer. now it printed the first line and then died with "Cannot find method 'Nil' on object of type List" 21:31
moritz pr\o/gress
MasterDuke died here: github.com/rakudo/rakudo/blob/nom/....nqp#L2974 21:33
gist.github.com/MasterDuke17/a19a5...2f048db905 21:53
so that's the AST and diff for removing make_topic_block_ref, and call()ing the result of p6capturelex inside an immediate block 21:54
it's printing the first line, but then seems to be executing the result of the say 21:56
yep, because "-ne 'sub { say "hi" }'" prints "hi" for every line in the file i give it 21:59
moritz MasterDuke: what if you remove the whole my $body := QAST::Block.new(...) and stick $code straight into the :op<while>?
MasterDuke building that now 22:02
MasterDuke would buy a beverage of choice to whoever brings the build down to less than a minute 22:03
