I'm still not clear on what your problem is or why you don't like
"from foo import bar".  FWIW our current project is about 330,000
lines of Python code.  I do a ton of work in the interpreter--I'll
often edit code and then send a few lines over to the interpreter to
be executed.  For simple changes, reload() works fine; for more
complex cases we have a reset() function to clear out most of the
namespace and re-initialize.  I don't really see how reload could be
expected to guess, in general, what we'd want reloaded and what we'd
want kept, so I have a hard time thinking of it as a language problem.
