Not 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. |

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.
