Is there any semantic difference between
BUILD_TUPLE 0 LOAD_CONST <code object ... > MAKE_CLOSURE 0
and
LOAD_CONST <code object ...> MAKE_FUNCTION 0
?
In other words is there any difference between a function and a closure that doesn't capture anything? Is it just a speed optimization for a common case?

It probably has more to do with the fact that nested scopes with added much later in Python's history than functions.
