The problem i have is to see which statements modify my data at execution

because of branching. You can never tell before hand which branch execution
will follow.

How might I subclass list without this error?
This is the code:

series_list = list.__new__(cls, *args)

Whoops. I should read more carefully. I thought he said the path to the module

If you want an absolute path (rather than a relative path), use:

I would find this more useful if the path will be passed around.

Based on other feedback I am leaning towards not using any IDE for the moment.
Python seems well adapted to that kind of workflow, as well as an impressive
portability - every bit as good a Java from my tests so far.
