in reply to Simple inheritance question

The main problem here is that you don't have a constructor for package One, so there's nothing for package Two to inherit. There are a lot of other little things with the code (like the fact that test() is a simple sub rather than a method, for example) which suggest the Perl OO tutorial perltoot might be a good item for you to read for a handle on how objects are handled in Perl.

Edit: I answered the wrong question and with an inaccurate answer. Then again, I learned something new about Perl and how it handles inheritance, so it wasn't a total loss.
