Jim has been good enough to write up a PEP for his proposal, so if you
have a counter proposal I suggest you do the same.

Personally, I don't like the slice idea because the common usage would
be:

  for i in int[:len(sequence)]: ...

Which is hardly more readable than:

  for i in range(len(sequence)): ...

Vs. the proposed:

  for i in len(sequence): ...

+1 for PEP 276 from me.
