The point is that creating a class object every time you want a
closure is pointlessly wasteful. There is *no benefit whatsoever*
in doing that. If you think there is, then it's probably because
you're trying to write Java programs in Python.

An important difference between Python and Java here is that in
Python the class statement is an *executable* statement, whereas
in Java it's just a declaration. So putting a class statement
inside a Python function incurs a large runtime overhead that
you don't get with a Java inner class.
