Although I think PyPy also recognizes this case and makes it as

How can pypy possibly know that the user hasn't assigned some other

It doesn't really need to. The optimization isn't applied when the
compiler sees the name "range" being called. It's applied after the
object the default builtin name "range" is bound to is called.
