I have a bunch of databases, but I also have the situation where, depending on what I'm doing, I need to connect to DB foo as bar one time, but baz another. I wasn't able to find in DBIx::Connect's docs how that would happen, programatically.

You're right, programmatically is out the window. You would have to have a label for each case, e.g:

[hohoho_as_foo]
dsn=dbi:mysql:dbname=hohoho
user=foo
pass=foozle

[hohoho_as_bar
dsn=dbi:mysql:dbname=hohoho
user=bar
pass=baz

Of course, again, with Resources, you would be able to default and inherit as one jolly well pleases, which is why I have my eyes set on it for a rewrite/forking of DBIx::Connect

Carter's compass: I know I'm on the right track when by deleting something, I'm adding functionality.
