Kaiepi net::icmp's far from trivial to implement so i'm going to get started on net::nntp instead for now 01:16

Geth rakudo: 89055755e2 | (Elizabeth Mattijsen)++ | src/core/Str.pm6
Add "count-only" method to Str.Lines/Words iterators

  - makes Str.lines(:count) / Str.lines.elems about 2x as fast
  - makes Str.words.elems about 4x as fast
  - makes both a *lot* more allocation friendly		 09:05

Geth rakudo: 86468e1ecc | (Elizabeth Mattijsen)++ | src/core/Str.pm6
Fix Str.Lines/Words iterator's count-only

  - doing a count-only should *not* affect the iterator status
  - makes it also about 5% faster
  - also fix typo in Lines iterator, which caused an extra infix:<,> call		 12:30
rakudo: 070780e04f | (Elizabeth Mattijsen)++ | src/core/Str.pm6
Add Str.Lines/Words bool-only method

  - makes Str.(lines|words).Bool O**0 (aka independent of size of string)		 12:51

Geth nqp: 715ae5d871 | (Tom Browder)++ (committed using GitHub Web editor) | examples/use-hashes.nqp
add another hash op example
 13:50
pmurias m: say(("@" ~& " ").perl) 14:02
camelia "\0"
pmurias according to synopsis we would want to return a empty string here 14:03
m: say(("ab" ~& "a").perl)
camelia "a"
timotimo do the tests specify anything?
pmurias checks
timotimo: I don't think so 14:05
I could change the js implementation and see if they pass ;)
timotimo why not :)
pmurias * still pass
timotimo: the tests don't specify anything 14:14
is #perl6-dev or #perl6 the place for language design questions 14:15
timotimo either should be fine 14:18
pmurias TimToady: what should "a" ~^ "a" return, and also what about "a\0" | "a\0"? 14:19

pmurias timotimo: just skipping trailing null seems to make the most sense logically to me (we just assume both strings are infinite and zero padded when they are of different lengths) 14:26
timotimo: OTOH I'm not sure what the use of ~&, ~|, ~^ other than it being in place because it was a Perl 5 feature

TimToady pmurias: I don't think the bitops should be required to trim trailing nulls, but are allowed to truncate the result when they know the rest of it would be "\0" 15:36
which primarily affects ~& so that it is allowed to return a result the size of the shorter argment 15:37
I note that in p5, "a" ^ "a" returns "\0", not "" 15:38
and "a\0" | "a\0" returns "a\0" 15:39
so that's the policy p5 follows, though one could argue that reduction to minimal form should be automatic 15:41
otoh, often you're dealing with a bunch of bitmaps of the same length, so maybe it's wasted effort, and the user can always strip nulls if they want 15:42
anyway, this is one of the few areas where my inclination is to torment the user on behalf of the developer :) 15:44
on the gripping hand, if anyone is seriously using such bitops in p6, they should really be using Buf types rather than Str types 15:51
