Can you tell I'm tired? I recreated the test I ran the test earlier a
"little" too fast. Here's what I should have said:
I realize that, but it doesn't explain the difference between
>perl -lw
my %h = map {
my $x;
(undef, undef)
} 1;
^Z
Use of uninitialized value in list assignment at - line 2.
and
>perl -lw
my %h = (
(undef, undef)
);
^Z
Use of uninitialized value in list assignment at - line 1.
The assignment didn't move, so why did the warning?
