Maybe the wording "module testing" was to sloppy

Real module testing requires a test suite, not a sub at the end of the file.

I meant rather "module demonstration" or "proof of concept" testing, where module.pm and user.pl are packed into the same file, like when posting an example on perlmonks.

Thank you for the interesting code, but it's significantly un-easier for my case, might help me in other occasions though.
