Agreed.

For the next Capon version I'm doing this: Filenames and line numbers
are encoded in function names, and exceptions are intercepted and
patched.  This works well; the only drawback is that patched
tracebacks (presumably, haven't tried it) don't play well with pdb.

I'll see if I can factor this functionality out into a separate module
for reuse.
