It set me to thinking:

Python should never require declarations. But would it necessarily be a
problem for Python to have a variable declaration syntax? Might not the
existence of declarations simplify some aspects of the proposal and of
backwards compatibility?

Along the same lines, might a new rule make Python code more robust? We
could say that a local can only shadow a global if the local is formally
declared. It's pretty rare that there is a good reason to shadow a
global and Python makes it too easy to do accidentally.
