[Python-Dev] confusing exec error message in 3.0

[Fredrik Lundh]

(using 3.0a4)

 >>> exec(open("file.py"))
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: exec() arg 1 must be a string, file, or code object, not 
TextIOWrapper

so what's "file" referring to here?

(the above works under 2.5, of course)
