exec src in {}, {} strangeness

[Stefan Seefeld]

hi there,

I have trouble running some python code with 'exec':

t.py contains:
class Foo: pass
class Bar:
    f = Foo

From a python shell I do:

>>> f = ''.join(open('t.py').readlines())
>>> exec f in {}, {}
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<string>", line 2, in ?
  File "<string>", line 3, in Bar
NameError: name 'Foo' is not defined

However, when I use the current global and local scope, i.e.
simply 'exec f', everything works fine. What am I missing ?

Thanks,
                Stefan
