I have the following line in a subroutine (using strict, of course):
 my $item = $self->grid($x, $y) and push @{$self->{'select'}}, $item

[download]
I get the error, "Global symbol '$item' requires explicit package name..." If I change the code to:
 my $item;
 $item = $self->grid($x, $y) and push @{$self->{'select'}}, $item

[download]
or to:
 if (my $item = $self->grid($x, $y)) {
   push @{$self->{'select'}}, $item
 }

[download]
the error goes away. This behavior mystifies me. Isn't the use of $item after the and in the first example in the same scope as the my declaration? If not, why not?

I'm using ActivePerl 5.8.4 under Windows XP.
