For what it's worth, I'm -1 on any change that makes range(10**10)
an error. I'd like to be able to write
for i in range(n):
...
without having to stop and worry about whether n is always going
to be small enough to avoid an exception, and what to do if there's
a possibility that n is large. The common case of range should
have a small mental footprint.
Indexing a range object, or taking its length, are surely much rarer
than simply iterating over it; I don't think the problems with indexing
and length are a good reason to impose restrictions on the use
of range as an iterable.
