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
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.
