I notice that rosh doesn't seem to exactly have the same initialization behavior as ipython. For example, in ~/.ipython/ipythonrc, I have the line: importmod os sys
So if I start ipython, I have the os module available in the interactive namespace. But with the same setup, starting rosh does not make those names available.
This is probably a bug in rosh. The rosh loader for the shell needs to import os and sys. In order to be 'clean', it then deletes os and sys.
Here's a patch that I think resolves this peculiarity (needs more testing):
