moritz_ good morning 08:15

moritz_ forgot to start cron in the chroot where the rebuilds run 08:18
SpiceMan hmm, trying to do Class Foo { for %hash.kv -> $k, $v { has "$k" is ro = $v } } # sadly not working, any pointers? 08:39
SpiceMan has some Moose background
moritz_ 'has' is compile time in Perl 6 08:40
SpiceMan: just use a hash as attribute
SpiceMan was giving HTTP::Status a try. in p5 it exports a bunch of constants, and felt like avoiding that, but thought it would be nice to have $s = HTTP::Status.new; say $s.HTTP_OK; # 200 instead 08:42
moritz_ just write methods 08:43
method HTTP_OK() { 200 }
constants don't work properly in rakudo yet 08:44
you can also do somethiing like
BEGIN { for (a => 1, b => 2).kv -> $k, $v { MyClass.^add_method($k, method () { $v }) } 08:45
]
erm, }
SpiceMan great, I like that :p

S05:501: "With the new C<:ex> (C<:exhaustive>) modifier, the current regex will match every possible way (including overlapping) and return all matches in a list context, or a disjunction of matches in item context."
seems that part of the spec hasn't been reached by the good news of the demise of wantarray and context dependence. 21:13
either that, or I'm overinterpreting that demise.
flussence wouldn't that behave the same as :g ?
masak anyway, I question the usefulness of a disjunction of matches.
flussence: no, because :g never overlaps.

flussence no, I mean, the list contextishness of it
(did we ever figure out what to do there?)
masak checks 21:15
the semantics of :g doesn't seem to be defined by S05. 21:16
which means... it's like in Perl 5. which means, no junctions.
flussence I recall there being a conversation here exactly because there's no wantarray for :g either...
masak I'll be honest. I don't think junctions belong in the regex machinery. 21:17
colomon flussence: that sounds familiar to me too.
I think it's been causing trouble for moritz_++
masak if you want a disjunction, just prefix the match with 'any'.
