Not explicitly. But in the course of conversation I might refer to
Napoleon, meaning Napoleon Bonaparte (1769 - 1821) or Napoleon III (1808
- 1873). There would then be an implicit 'rebinding' of the name Napoleon.

My point was to get away from a model for Python which was built on its
likely implementation and to hint that we can build one using the naive
concept of 'name for a thing' instead. IOW, 'call by value' is an
unnecessary obfuscation of what *actually* happens (even though it may
describe accurately the artifacts employed by an implementation)
I'm glad that you thought about it!
