Further to ikegami's post, in case you are not using 5.10 yet, the following 'hack' works as well:
use strict;
use warnings; 

{   # Outer block

    my $keeps_value = 0;

    sub mysub {
        print "$keeps_value\n";
        $keeps_value++
    }

}   # End of outer block

mysub();
mysub();
mysub();

The varibale $keeps_value is not visible outside the block.
