Re^2: Why does the first $c evaluate to the incremented value in [$c, $c += $_] ?

[derby]

Wild guess here but since the anonymous array is on the right side of a list operator, then the comma has really low precedence -- lower than assignment. By adding the +0, you give both terms equal precedence so it goes back to leftward precedence? Well ... that's my guess.

update: what Eily says makes better sense given the simple example of

use Data::Dumper;

my $c = 0;
my $d = [ $c, $c += 2 ];

print Dumper( $d );
