wander why some of these guys' contents are 'Pod::Block::Para'?
02:20 mtj_ joined
wander when using `=headn` or `=item`, i want a one line head/item 02:21
02:21 Cabanossi left
wander especially, we provide classes `Pod::Heading` and `Pod::Item` for them 02:22
02:22 Cabanossi joined
wander however, we treat their contents as `Pod::Block::Para` 02:22
github.com/perl6/Pod-To-HTML/blob/...#L214-L239 02:26
that is why we have to use `:$inside-heading` to check if a Para is inside a Heading
too tricky

Anthony_ Hey folks, I tried to port a simple K (APL derivative) one-liner (`primes:{1+&2=+/~(1+!x)!\:/:1+!x}`) to Perl 6 and my P6 solution is much much slower (and more verbose). Do you know how I could fix any of this issues? `sub primes($n){grep {2 == [+] $_ <<%%<< (1..$n)}, 1..$n}` 10:29
moritz m: sub primes($n) { (2..$n).grep(*.is-prime) }; say primes(50) 10:30
camelia (2 3 5 7 11 13 17 19 23 29 31 37 41 43 47)
Anthony_ moritz. Yeah that would of course work with a very high probability 10:31
but I'm trying to transcribe the algorithm
there are waaaay better ways to calc primes
so it's really the procedure that matters for me
moritz I don't see anything obviously wrong with your Perl 6 translation 10:32
Anthony_ okay
I can understand why Perl6's performance is worse in this case
it is obviously not tuned for that style
but I thought there might be some fundamental issue with this
moritz and if you are chasing characters, you can replace << with « 10:33
Anthony_ the only real-world language with heavy use of unicode :)
I love it :D
