Holding a 5MB string in memory is hardly onerous.

The problem is entirely down to creating a huge list of scalars each containing a single character in order to count those characters.

    You're right. :)

    This really should be a job for tr///, shouldn't it?

    my $string = '5mb of stuff';
my $count = $string =~ tr/\0/\0/;

    (I probably just missed seeing that proposed somewhere within the thread.)

    Update: Ah, I see it's the first thing you proposed (good job). This is probably a good time for me to walk away from the keyboard for awhile. ;)
