use strict;
my $foo = 1;
my $fum = 1;
print STDERR "variables are now: $foo $fum\n";
{
my $foo = 2;
$fum = 2;
&foo();
print STDERR "variables are now: $foo $fum\n";
}
sub foo {
print STDERR "variables are now: $foo $fum\n";
}
Resulting:
variables are now: 1 1 variables are now: 1 2 variables are now: 2 2as you wanted
