Yes, that's common. List processing via variadic arity functions is an explicit feature of Perl.
- prodigal_erik 12y agoNot explicit enough. Perl is the only language I've ever seen where sub f { return 1, 2 } my %x = (a => f(), b => f()); produces a three-element hash that has '2' as a key and 'b' as a value with no warnings. "Even offsets are keys" is far more error-prone than an actual syntax for hash literals, and splicing a list (not a hash!) into a hash doesn't need syntax this terse because it's hardly ever what I wanted. I think even PHP is more sane here.
- chromatic 12y agoI think even PHP is more sane here. I'm not sure how an appeal to PHP as lowest-common-denominator of language sanity argues against understanding the return values of functions you call.
- prodigal_erik 12y ago> understanding the return values of functions you call Sure you should. But confusion between keys and values isn't useful, so there's no reason for a subexpression to be able to do that, and in PHP it can't.
