Oops! Sorry for ignoring your main question.
If you don't declare the variable INSIDE THE LOOP, \@temp will be the
same reference every time you use it. So if you do
@temp = ();
push @ar, \@temp;
you eventually just get an array of all the same reference to the same
other array.
{ # loop body
my @temp;
push @ar, \@temp;
}
creates a new array with a new reference, every time.
Note that if you move the declaration of @temp outside the loop, the
problem comes back. So it's not a "global vs. lexical" thing.
