timotimo what's the standard answer to someone saying "perl6 destroyed perl5 because people started saying 'i'll wait for perl6 before i continue doing stuff'"? 00:03
00:04 colomon joined
TimToady "no, perl6 resurrected interest in perl5" 00:04
the reason perl6 was started in the first place is that people *already* recognized that perl5 was stagnating 00:05
that was precisely Jon Orwant's point with the mugs 00:06
lizmat read the backlog
TimToady and that's the nice answer :)

lizmat will see if there is a solution for %<a><b>:exists that would not need Any.exists, and which would not slow down all {} accesses 00:08

jnthn lizmat: For now we could constraint it to :U on the invocant
jnthn gets some rest also
'night o/
TimToady nighty
lizmat no, that doesn't work, because the U: is exactly what we need for %h<a><b> 00:09
ah, me is sleepy
yes, you're right: U: should do it, but then the error message gets confusing
"Invocant requires a type object, but an object instance was passed" for 42.delete(42) 00:10
LTA error message
and oddly enough, if I add the U:, I get spectest errors with exactly that error
not sure what is going on there, will check after some sleep 00:11

TimToady remembers his senior year fondly 02:11
any idea what you're doing next year yet?
Mouq …not particularly. ATM I'm wishfully thinking something in Engineering at UPenn 02:13
diakopter that's, like, ivy league and stuff 02:14
TimToady I'm sure there'd be plenty of worse choices
though you get more personal attention at a smaller school--it's all tradeoffs
Mouq Really? I don't think of UPenn as ivy league. 02:15
TimToady yes, well, diakopter is from Texas, so you have to cut him some slack :P
diakopter heh.
ivy league is well-defined... 02:16
Mouq I'm a PA resident, so it's a little different
TimToady schools with ivy on them, I know...
yeah, I figured you was in PA from the traceroute that stopped somewhere in the middle of PA
but I didn't want you to think I was stalking you, so forget I mentioned that :)
Mouq heh, nah, traceroute's fun 02:18
TimToady mostly I just wanted to know which timezone you're in
so's I could properly claim to be west of you 02:19

TimToady nope
hafta do that with a subset type now
subset IR where Int | Rat; sub f (IR $a) {...} 03:53
ml Hmmm...mislead by Wikipedia again. Thanks!
TimToady was an old idea that didn't work out
in particular, it'd be terribly ambiguous now that we have |c to bind captures 03:54
likewise we have &foo to bind routines, so & doesn't work either
alternately, you want sub f (Real $a) {...} there
since Int and Rat share that role 03:55
(I believe)
r: say Int ~~ Real; say Rat ~~ Real;
camelia rakudo 1fca64: OUTPUT«True␤True␤»
ml But Real would allow inexact numbers as the argument? 03:56
TimToady well, most numbers are 03:57
ml That's true :-)
TimToady and even Rats won't maintain their exactness if you overflow their denominator 03:59
and FatRats that do keep precision have performance issues when they keep precision
(unless you keep them on a diet) 04:00

masak in other news, I'm enjoying pipeline.corante.com/archives/thing...work_with/ today. if you're looking for good, engaging writing about dangerous chemical compounds, this is it. 11:42
I wish I knew how to write like that. I also wish my chemistry classes were a bit more like that.
cognominal I anticipate that eventually the AST will be the reference and people will deparse them as they see fit. So everyone can have his own private language (syntax wise) without bothering the others. In a sense, that will be an answer to a Wittgenstein argument. en.wikipedia.org/wiki/Private_language_argument
masak what better way to make a schoolchild interested in chemistry than by telling about all the horrible ways it's possible to screw things up?
cognominal: if we ever reach the "everyone can have a slang of their own" state with Perl 6, it will be an interesting thing indeed. 11:43
like a CPAN but on the language level. 11:44
I'm curious about how feasible it'll be to combine/compose slangs.
we already do that with routine and type definitions, for example.
cognominal I don't think they will combime because they are very unlike haskell grammar combinators 11:46
what is strange is that everyone is speaking DSL these days and I am not sure people provide tools to do that (except haskellish combinators) 11:48
perl 6 will.

lizmat jnthn: the spectest says: is ([!==] ()), Bool::True, "[!==] () eq True";
jnthn hmm 14:08
masak lizmat: that is correct. 14:09
let me explain.
"innocent until proven guilty"
you start by assuming all things are unequal, and then iterate until you find a case that disproves this.
empty list; zero iterations.
the truth holds.
lizmat ok, so any bool reducing metaop with an empty list should return True 14:10
masak you cannot argue "by consequence, [the opposite of [==]()] should be false" -- all [op]() where op is a comparison op are True.
right.
(I'm on a train -- slight lag) :)
lizmat ok, just getting some clarity is good

lizmat shouldn't that be True?
masak correct.
no, False.
|| is not a comparison op.
so the above rule doesn't hold. 14:45
in the case of ||, we're looking for a True value.
so the algorithm is "False until found True".
FROGGS if [||] () would be True it could never be false
