It looks like I've started some sort of a theoretical dispute :).

Sorry about that, fellows.

What I meant is that warnings are important, and they should have be used, at least in the installation test scripts, especially in early stages of development.
Why it is important should be clear immediately if you try to run the example script with the "-w" in the shebang. You get an annoying list of "uninitialized value" this, "Drive has not implemented DESTROY for DBI" that.
My point is that such trivial mistakes would have been easy to catch if a "-w" was used in the tests.
I didn't mean to blame anybody, just to "warn" (pun unintended) the readers about possible drawbacks if they wanted to have a look at the module.

Anyway, just to have a happy ending, :) I've contacted the author. He has acknowledged the problems and he's going to take care of them.
