It's not necessarily bad, it depends on how you go
about it. If you always "import Modulename" and then
qualify all the names you use from it, there usually
isn't any problem.

Another technique which is useful for avoiding
circular import problems is to place import statements
inside the functions where they're used, rather
than at the top of the module.
