That's probably because I had switched the two dictionaries
in the exec statement -- here's a corrected, simpler version:

>>> def with(obj,stmt):
...   exec stmt in globals(), vars(obj)
...
>>> with(x, "pak=23; pok=24")
>>> x.pak
23
>>> x.pok
24
>>>

In lieu of globals() one surely wants to default to the *caller*'s
globals, sys._getframe(1).f_globals, of course.
