masak realizes that 'also' is a kind of assymmetric dual to '.each' 10:31
from the description at perlgeek.de/blog-en/perl-6/tidings-....writeback , I don't immediately see why I'd want to use 'also' rather than 'and' or '&&'... 10:32
hm, ISTR infix:<also> was subsequently named infix:<andthen>... 10:33
jnthn I think andthen probably captures the ordered semantics better.
masak ok; in what way? 10:34
hm, from S03 I gather that it's sort of a loose opposite of // 10:35
jnthn "jnthn is drinking pivo and also vodka" vs "jnthn is drinking pivo and then vodka" - in one it could be the two at once (eww) but in the the second it's much clearer it's one then the other.
masak and 'orelse' is a loose version of //
jnthn: but 'test1() and test2()' is sequential too, and always was. 10:36
10:36 JimmyZ left
masak ok, 'andthen' does things with INVISIBLE BLOCKS. 10:36
jnthn and failures
masak a bit like a monad would, I guess.
jnthn That's a scary world. 10:37

phenny jnthn: Sorry, no results for 'INVISIBLE BLOCK'.

phenny U+2062 INVISIBLE TIMES (⁢)
jnthn :-)
There's still (to me) no difference between a block and a thunk, fwiw.
moritz_ masak: btw after our discussion about joining the community, I backlogged very far to see what you first asked in here... it was what a thunk is :-)
jnthn: there should be one, in that a thunk does not introduce a scope 10:38
jnthn (at the "what they compile to" level
moritz_: I don't have a way to implement that.
Well, not easily at least.

moritz_ jnthn: that's another matter
jnthn I hadn't really regarded that as a thunk.
To me that kinda isn't one.
I mean, it's just syntactic sugar for an "if"-ish kinda thing
But we don't have to run the code at some unknown point in the future and called from a different place. 10:40
Hmm...maybe we need to distinguish the two somehow.
moritz_ maybe
or maybe my idea of "thunk" is not yet fine grained enough 10:41
jnthn Or maybe mine isn't either. :-)
Or our ideas of thunks don't entirely overlap.

masak TimToady: ^
jnthn ooh! 10:43
From S05:
This is not a normal assigment, since the right side is evaluated each
time the substitution matches (much like the pseudo-assignment to declarators
can happen at strange times). It is therefore treated as a "thunk", that is,
as if it has implicit curlies around it.
Thus thunk = implicit curlies = scope? :-) 10:44
10:44 clintongormley joined
moritz_ that's the big question 10:44

Maybe the distinction is thunk vs "thunk" ;-)

masak smells a bug
moritz_ well, I think the parcels should flatten in list context

jnthn aye 12:06
colomon I think we still have flattening issues...

12:09 xinming left 12:10 JimmyZ joined
JimmyZ hello, moritz_ 12:10
colomon Z doesn't even try to return the pairs as a parcel. 12:11
moritz_ good localtime() JimmyZ
colomon I have a vague memory that bad things happened when I did try to return the pairs that way. 12:12
JimmyZ I saw there were two Announce of release #27 on rakudo.org
moritz_ JimmyZ: aye. Before I wrote the second, the first one would not show up
I fear that deleting one takes down the other
JimmyZ oh
takadonet1 morning all
12:13 writer joined
colomon o/ 12:14
12:14 ruoso joined
masak takadonet1: \o 12:14
writer Hi everyone
takadonet1 writer: hey 12:15
writer tried to run a program from the perl6 book and got this error: pastebin.com/1d5VmLCt
hello takadonet1 :)
masak writer: I'll have a look. we don't expect all programs from the book to run on master yet...
writer Oh, okay.
moritz_ writer: it's a known problem of the current rakudo
writer BtW, I'm running rakudo 2010.03 with 2.2.0 12:16
moritz_ writer: you can work around it by changing line 27 to read #
my @sorted = @names.sort({ %sets{$_} }).Seq.sort({ %games{$_} }).reverse;
masak grumbles
a paste service that can't copy/paste properly has missed something.
moritz_ with rakudo 2010.01 it should work (after that some regressions were introduces by a huge rewrite) 12:17
writer thanks moritz_ masak
m6locks rakudo: role A { method foo($arg is rw) { $arg = 42; return $arg; } }; say A.foo(6) 12:18
p6eval rakudo 0dcfc6: OUTPUT«Cannot assign to readonly value␤current instr.: '&die' pc 17192 (src/builtins/Junction.pir:399)␤»
writer so ideally, you don't need '.Seq' ?
m6locks shouldn't that argument be rw?
moritz_ writer: no, you don't
m6locks: how do you write to the integer 6?
writer okay, thanks 12:19
moritz_ m6locks: in ideal Perl 6, the binding of the signature would already fail
because 6 is not writeable
in rakudo only the assignment fails
m6locks ok, but can i has rw arguments at all? 12:20
moritz_ sure
jnthn Yes, but you need to pass in a variable. :-)
The binder should akshually check it for you... 12:21
m6locks rakudo: role A { method foo($arg is rw) { $arg = 42; return $arg; } }; my $six = 6; say A.foo($six)
p6eval rakudo 0dcfc6: OUTPUT«42␤»
m6locks ok, workd
jnthn rakudo: say [min] <man e kass> 12:22
p6eval rakudo 0dcfc6: OUTPUT«e␤»
snarkyboojum masak: pity about the foreach issue you noted 12:25
colomon alpha: for <a b c> Z <1 2 3> -> $x { say $x; }
p6eval alpha 30e0ed: OUTPUT«a␤1␤b␤2␤c␤3␤»
colomon > for <a b c> Z <1 2 3> -> $x { say $x; } 12:26
a 1
b 2
c 3
(that's with Z patched to be Z,)
moritz_ doesn't think that's correct
colomon as far as I know, alpha is correct here.
masak snarkyboojum: yes, well, Perl tends to favour a "liberty at all costs" party line. it'd be strange if you were allowed to call your subs "sub", "loop". "while". "class" and "multi", but not "foreach" :) 12:30
snarkyboojum I'd still like an awesomized error message tho :) 12:31
jnthn Just change it to
masak yes, me too.
jnthn <sym> <!before '('>
or better, <sym> <.nofun> 12:32
snarkyboojum excellent :)
jnthn btw
