Store the bulk on disk or in a DB and use several smaller hashes to do the
merging. After which I can retreive the bulk from disk/db while looping over
the resulting combined hash. (note to self: must not fo

It's like normal golf, only with Perl. You try to finish the program
(or the 18-hole golf course) in as few (key)strokes as possible. In

With while(), the $_ is already local. Wouldn't using that 'local'

my $i = 5;
$_ = 'Hi there!!!';
while ($_ = $i--) { print }

my $i = 5;
