interesting Namespace problem

[Stephen]

    The first way to do this that pops into my mind is the following. It
will execute the import statement in the global namespace. This seems
inherantly evil, There's got to be a better approach to what you're doing
this for. Heh. Maybe its just because I find 'exec' to be strangely evil all
on its own.

def import_module(module):
    exec "import %s" % module in globals()
    do_stuff("print os.sep")
