What about using the reimport library?

Cheers,

I have not because of an assumption that "import" imports the module just once. In fact this still works that way:

here is a terminal 1:

$ cat > a.py
a=1
$ cat > a.py
a=2
$


and terminal 2:

>>> from a import a
>>> a
1
>>> a
1
>>> from a import a
>>> a
1
>>>

In spite of changing a.py in fly, the imported a is still 1
