BBQ has asked for the wisdom of the Perl Monks concerning the following question:
I have come across a philosofical issue. Is there a good method for detecting if a module has been loaded from within a subroutine?
In more detail: I am planning in writting a common authentication subroutine what will be used across several utilities being implemented on my intranet.

Now, since some of these scripts are already written, and some of then don't use DBI, I was planning on writting something in the lines of:
