Do you want something you can const_cast away, like in C++, or do you
want something that's guaranteed to be constant? The former is
accomplished idiomatically in Python by using all uppercase variable
names, and then not assigning to them (sort of like C++ declaring
something const and not const_casting it away). Neither C++ nor Python
has reliable ways of ensuring that something cannot be changed.
