scope creep

inject.py

def inject(**vars):
    def decorator(fn):
        def fun(*args, **kwargs):
            gls = globals().copy()
            gls.update(vars)
            new_fn = type(fn)(fn.__code__, gls)
            return new_fn(*args, **kwargs)
        return fun
    return decorator

@inject(q=10, z=11)
def test():
  return q + z

I'm not sure why any sane person would ever do this. But it is fun to know you can.
