(what kind of files are you using? enumerate overlows after more than two  
billion lines... is that "soon" for you?)

I'm afraid neither iterate nor itertools.count will generate a long  
integer; upgrading to Python 2.5 won't help. I think the only way is to  
roll your own counter:

lineNum = 0
for line in f:
   ...
   lineNum += 1
