Summary: Enumerate with step

Initial Comment:
I tried to do:

enumerate(letters)[::3]

...when I found out it didn't work. And it's different
from:

enumerate(letters[::3])

It would be nice if enumerate had a 'step' argument by
default, without subclassing it by hand.

Guido rejected the step argument to keep it separate from
slicing.

For a workaround, use itertools.islice():
    islice(enumerate('hello'),0,None,3)
