[Columbus-pm] Fwd: MLDBM-like module

[Michael Frager]

Actually, I haven't decided on a name for the version I'm going to release.

I'm considering: Tie::SQL or DBIx::Deep or something like that.

Right now the current modules are tied into my own webapp framework and need
some changes to be made to work independently and thus viable for CPAN.

However, the underlying concept is sturdy and it is something I think a lot
of people would benefit from, so my goal is to push toward a release within
a month.

Also, though this module is the thing that other people would find useful
immediately. I've been working on some other things that are also very cool
and contain ideas that other Perl programmers might want to learn about.

My hope is that I can show some people in Columbus.pm what I've been up to
(beyond the "tie" module), see if they like it, and then head toward a
release of the whole thing in time for YAPC 2010.

On that note, let me put my vote in for the Winking Lizard (on Bethel). What
date/time would that meeting be?
