Re: [+] on a list... with a Junction

Hi, It's just a bug and sum is too eager about restricting the types to numeric. If you report it, I'll take a look in the next couple of days. Just email to rakudobug@perl.org

EDIT: never mind. Just fixed it in https://github.com/rakudo/rakudo/commit/8d04bec

Thank you for the mention and the bug fix. I was waiting to get back to my computer to write up the bug report (something, something, work computer, personal email). I'm not yet familiar enough with the code base to be certain, but I wonder if that change will resolve the tangential bug(?) of `say [+] (1, 2\|3, 4);` (does it do magic to map `[+]` to `.sum`?)

Re^3: [Perl6] [+] on a list... with a Junction by Zoffix (Acolyte) on Nov 25, 2016 at 19:42 UTC
Yeah, that is fixed as well. The `[+]` metaop is special-cased to become `sum()` since it's pretty common and we have other optimizations for `.sum`, like the one on Range objects for example: `say sum 1..999999999999999999999999999; # 499999999999999999999999999500000000000000000000000000` [download]	[reply] [d/l] [select]
