Hi all,
I was wondering if there is a way for Perl to give me a warning if I
redeclare a variable in a different scope (and thus masking the outer
one). Just spent some time debugging this (which was obviously not my
intention to give two variables the same name)...and I guess it is a
silly mistake that I would do again and again. :-)
i.e., This gives a warning:
my $foo = 0;
my $foo = 1;
But this works:
my $foo = 0;
{
my $foo = 1;
}
Thanks!
Ray
