- masklinn 11y agoI really couldn't tell you. I guess "it's perl, we can"?
- hahainternet 11y agoCould you explain why you think this is awful? Perl 6 has proper sets, bags and the appropriate operators for 'normal' set operations too.
- raiph 11y agoOne that I recall that I'm hoping still applies is having a syntactically and conceptually lightweight way to express semantically parallel computation logic. Given the code: junction1 = val1 | val2 | val3; junction2 = val4 & val5; if junction1 op junction2 { ... }; the compiler is free to fire off several threads, or set up a lower level SIMD parallel process, with short-circuiting, to compute the conditional result.
- awwaiid 11y ago* Seems kinda cool * Makes $x == 5|6 look kinda cool * $string ~~ /<first>/ & /<second>/ & /<third>/ # matches all three regexes. huh. kinda cool * (5|6).foo maybe we can do that in cpu-parallel (it doesn't now)? That might be kinda cool * sub is-prime($n where $n > 2) { $n % none(2..sqrt($n)) == 0 } # Logical O(1) prime test if only you had that quantum-coprocessor? That... would be kinda cool * ... you might notice a pattern to the motivation for this feature :)
