In my build of perl 5.23.5 on recent debian i386 and its supplied List::Util 1.42_01, a program use strict; use List::Util 'min'; my $x = 7; my $y = 3; print "$x, $y\n"; ($x,$y) = (min($y), min($x)); print "$x, $y\n"; prints 7, 3 3, 3 where I expected it to be 7, 3 3, 7 which is what previous perl versions have given. I struck this digging around forI don't know if the fault lies in List::Util or in perl. Omitting the "min" so a plain swap ($x,$y) = ($y,$x) seems ok. Could something hairy happen on passing through min() ?
