I don't think it is either.

I used to think that

   fir i in x:

where (x) is an intreger, was confusing. But lately, I've found 
myself accidently spontaneously typing it myself instead of range(x)
so i guess it makes intuitive sense after all.

I agree this is too long. vThe last tinme this was discussed, the 
consensus was that it should be replaced by 

   for i in list.keys():

modelled on the dict.keys() method.

i've toyed with the idea of a fromto() function, where fromto(a, b)
returns the same as range(a, b+1). There could also be xfromto(),
like xrange().

I'm not sure if 'fromto' is the best name, mind.
