Ah, that's the missing piece! I keep thinking 2.5, 2.6, 3.0, and
forgetting that someone might make a 2.7 :) I bet I wasn't the first
one to be confused by this, nor am I likely to be the last.

Sure, given a 2.7

execfile( "file.py" )
Where is the open function?
I have it working under 3.0, not sure how to specify the encoding for
2.6, though, and this question is now off-topic for Python-Dev.
