OK, If you only import the functions not the whole module reload
won't work. But how about deleting the function and then
re-importing it? Wouldn't that do it?

You could even create a function to do that for you, maybe like:

def restart(fn, mod=mycalc):
    del fn
    from mod import fn
    return fn

And us it like:

>>> from mycalc import foo,restart
>>> foo(42)   # oops wrong result
>>> # go edit foo
>>> foo = restart(foo)
>>> foo(42)   # thats better...

This is untested pseudo code but it should work with a bit of
effort - eg. you may need to use the programatic mechanism for
re importing

Just a thought.
