They're not.  I'm trying to promote a pradigm of including a VERSION 
subroutine that
will croak (or at least die) when you ask for a non-forwards-compat. 
version.

In theory, you change the name when you change the itnerface, instead of 
merely
updating the version number.

Issue a new module name with the new interface, and maintain both 
versions for bugs.
