something like this might work:

if discrepancy and sys.stdin.isatty():
import code; code.interact(local=globals())

François, Fredrik:

I thought this would work, but it doesn't:

import os

if __name__ == '__main__':
discrepancy = True
if discrepancy:
os.environ['PYTHONINSPECT'] = "why yes, i'd like that"


A quick read of Modules/main.c shows that the environment variable is
checked at program start, not at end. Maybe this is a bug?

The slight, obvious rearrangement to Modules/main.c seems to work. I'll
propose it on python-dev.

It would be nice if the Python crew was willing to see this as a bug. A
program might also delete PYTHONINSPECT if it feels shy to get naked.
