Or, in my case, throwing away the Perl I had because I found I had
written something much more useful in Python.

A little bit of experience on a smallish (or largish!) from-scratch
Python project does of course make a difference: Perl and Python are
sufficiently close in many things that it's easy to get tunnel vision
when porting Perl to Python.  A little knowledge of Python idioms,
techniques, standard library modules, etc., gained outside of that
narrow context, goes a long way to prevent that.

OTOH, the often-mechanical nature of porting .pl->.py, and the great
flexibility of both languages, does certainly make it easier to
switch.
