I think that Raymond marked as "won't fix" because automatic float -> 
integer conversion has been deprecated since Python 2.3.0 (if not 
earlier), for exactly the reason you state.  It's dumb.

 >>> range(2.7)
__main__:1: DeprecationWarning: integer argument expected, got float
[0, 1]

Apparently file.seek doesn't have this DeprecationWarning though..  
Strange, that.
 >>> f.seek(3.6)
 >>> f.tell()
3L
