Messy, all of those... :(.

Usually, I'm using standard Python testing modules, but sometimes that is
just an overkill. Sometimes I like to do 'exploratory programming',
especially in the early phases of development - create a bunch of objects I
want to play with and do that from IPython. Only way I found out to
somewhat automate this procedure is to have a function that creates all of
the test objects, and then raises an exception at the end. IPython starts
ipdb, so I can work with the objects the function created (without copying
them back to the shell). But this somehow looks too hack-ish for me, so I
was wondering if there was an alternative...
Anyway, thanks for your answer ;).
