Presuming that the module name is , say,  test,  how is:

-pidname( test )

different from:

register( ?MODULE, self() )?

Also, how would you run multiple instances of the same module within the same run-time?
Your proposal may appear to solve one problem (that is, if one chose to call it a problem), but appears to introduce at least one more.
