Ok, it looks like I'll have to read up on how an @INC handler works (suggestions are welcome).

In the meantime, as per your test, I put 'use ifdef;' at the top of the module, and the vars I pass on the commandline now propagate. Just to make sure I understand the significance of this, let me see if I've got this right:

  1. -Mifdef=DEBUGGING on the commandline puts a handler into @INC
  2. use lib './perl5lib'; in foo.pl puts perl5lib into @INC
  3. use ifdef; in Bar.pm puts another handler into @INC

The last handler (added in step 3) can now get triggered because it is at the front of @INC. It also knows about perl5lib because it was added in step 2 before the triggered handler. It is also able to process the pod sections tagged with DEBUGGING because it was set in the original handler in step 1.

Am I even close? All this playing with @INC is pretty new to me, so forgive my ignorance.

Thanks!
