proposed antigravity

__doc__ = "Add fly function to namespace where module is imported"

class RealWorldLevitation(Exception):
    pass

def expose(obj):
    import inspect
    frame = inspect.currentframe()
    frame.f_back.f_back.f_globals[obj.__name__] = obj
    return obj

@expose
def fly():
    raise RealWorldLevitation('possible in http://xkcd.com/353/')

# so the usage of module is as simple as
>>> import antigravity
>>> fly()
# and there's some Python magic inside
