Unfortunately opApply doesn't not work well with all the other 
range-based functions.
Also that Enumerate code is for illustrative purposes, it's not 
meant to be good library code.

Generic programming must know if you are iterating only on items 
or on index-item pairs. As Python Zen says, explicit is better 
than implicit.

Yet Python designers have preferred to use enumerate instead of 
messing with the Python for.
