SPUG: How to deal with same name packages?

We've actually done something similar here but in a different
direction. All debug messages are written to a single debug object
which is shared across all modules. (When running anywhere but the dev
environment, writing to the debug object is essentially a no-op.) In
addition to holding debug messages, it also traps all STDERR output.
All messages are stored and then dumped out at the end of any html
produced.

I find it's a lot easier to actually see debug messages in the page
than to use a separate window which tails the error log. It also allows
for one to dump quite a bit more data without feeling overloaded, and
gives the added benefit of being able to easily search the output
(although one could presumably get the same by using less). Since the
output comes at the end of the page, it's reasonably unobtrusive. It
can also be turned off reasonably easily with a url parameter or a
cookie.
