colomon using gather and take like that flattens? 00:43
pmichaud well, it grabs each non-iterable
(so yes)

TimToady phenny: tell jnthn I'll be sitting there, but I might be writing my talk
phenny TimToady: I'll pass that on when jnthn is around.
pmichaud TimToady: ...if we let you. :-) :-)
benabik Is .&sub ~~ sub($_)? 00:45
pmichaud benabik: $a.&sub($b) is essentially &sub($a, $b)
TimToady the main thing is that order cannot be guaranteed with hyper take
so it only works for feeding to commutative operations 00:46

p6eval nom: OUTPUT«3 2␤»
TimToady hmm, that looks wrong
colomon \o/ # sin.t just passed locally in nom
TimToady a hyper is still supposed to return the values in the same order
it's only side-effect order that can't be guaranteed 00:54
(and take qualifies as a side effect for that purpose)
pmichaud: ^^
nom: my @a = 1,2,Mu; say @a>>.?succ.perl 00:55
p6eval nom: OUTPUT«Array.new(2, Nil, 3)␤»
TimToady definitely wrong
you can't shuffle the results 00:56
you can only shuffle the order of operations
pmichaud agreed, the results shouldn't be shuffled. 01:04
TimToady nom: say [1,2,3]».succ
p6eval nom: OUTPUT«2 3 4␤»
TimToady that works...
pmichaud > my @a = 1,2,Mu; say @a>>.?succ
2 3 Nil
looks like my patch fixes that.
it's exposing another bug, though.

maybe pod renderers can register with Pod::To when they load

tadzik maybe we should ship a Pod::To::Any module, containing a pod2any(@pod, $what) sub, which will do the dirty work 09:23

colomon the trig functions are really LHF at this point, I think. :)

moritz regarding exceptions and backtraces 12:14
the exception object needs to get hold of the backtrace somehow 12:15
so the runtime should call $ex.with-backtrace($bt) before storing the exception in $! (or $_ inside a CATCH block), and store the result of that method call 12:16
so the author of the exception can either go with mutable exceptions that return self in that method
or with immutable exceptions that can clone + add bt in one step 12:17
does that sound sane?
(the other day sorear++ asked if exceptions were mutable or immutable - that setup would allow both)
pmichaud don't Parrot exceptions hold a backtrace already?
I'm pretty sure exceptions are mutable, since we need to be able to mark them as "handled". Unless there's a handled and unhandled list 12:18
moritz just to be clear, that's a general Perl 6 design question
and yes, a parrot exception has a bt

JimmyZ wonders why list returns Mu but array returns Any 15:16
pmichaud arrays act like lists of scalar containers... and scalar containers default to Any 15:17
lists are just lists of objects, and if one isn't present then List currently returns Mu 15:18
we can switch that to Any if that would be better.
Mu feels righter to me at the moment.
TimToady lists are more abstract than arrays, so Mu is okay, unless it should be Nil
pmichaud yes, Nil would be another good choice. I didn't have Nil available when I wrote the List.at_pos code :) 15:19
I guess Nil makes more sense, since it indicates "absence of a value" 15:20
TimToady and Nil is appoximately the right abstraction level for a not-there list
pmichaud I'll switch it.

colomon just copying without the given
sbp ah, thanks. didn't know the given was just syntactic sugar for the $_ conversion 16:07
TimToady wonders how succeed decides to return when there's no topicalizer
PerlJam you could have just used $_ instead of $a to avoid mentioning the variable so many times too
TimToady I guess a sub "sets" $_ by definition 16:08
PerlJam I would have probably used explicit returns in colomon's version because otherwise it seems like it works because of careful conditional construction. 16:10

But ti's kinda long.
colomon long would be okay, it should be very rare for users to actually call it. 17:53
JimmyZ guesses there should be a test for 4799849 17:56
masak here's why .components would be nice and .reals sucks: for immutable types and especially math types, the query methods ask for a "part" or an "aspect" or a "view" of the object. .reals misses the mark, because there is a real part of a quaternion, or of a complex number, and it's not the whole set of components. 17:57
the analogy to a vector or something is flawed. 17:58
(besides which, a vector might as well be a vector of complex numbers, or of quaternions)
jnthn Sounds like it's .components then :) 17:59
