The claim wasn't that iterators are used infrequently,
but the functions in the itertools module.
The vast majority of the time, the only thing people
do with iterators is iterate over them.

This is wrong -- they won't return iterators, they'll
return *views* that can be indexed and otherwise used
as sequences or mappings. So this has nothing to do
with the proposal at hand.
