Another New module on its way to CPAN

[Liyang HU]

You can get it at:

    http://nerv.cx/liyang/perl/ForLoop-0.0.0.0.0.0.1.tar.gz

What does it do? One thing and one thing only: it takes a sub ref,
passing it a numeric value successively between two limits you specify.
e.g.:

    for_loop(1, 10, sub { print shift(). " of ten!" });

Hopefully, support for iterating over arrays will come in the next
release. Beta-testers are welcome! Please contact me for details!

Yes.

Repeat after me: map is good. Erasing map from one's mind is baaaad.
Mmkay?

Well, you can justify *anything* using existing modules in CPAN...
genocide, probably. I'm getting a distinct feeling somewhat akin to the
freshmeat ``My First Shell Script'' syndrome... asserting copyright and
specifying the license for one line of code is just silly[0].

How about actually merging hashes (dealing with key clashes), like the
module's name suggests it ought to do? Something like:

    my $ref = merge_hashref(sub { my ($a, $b) = @_;
        return $a > $b ? $a : $b }, $ref1, $ref2, ...);

later,
