Description: Improvements in this PR: No more relying on the string names to deduce the types of local variables. No more threading down the names of local variables from all functions and visiting: now the code has a local variable scope with a context manager. Specially for @lysnikolaou: I have actually managed to do #19745 (comment) and now we don't need all the specialized token functions. Just one for name, string and number. Now we have a class to represent function calls, making the code a bit more explicit and carrying metadata if needed. Also helps when debugging (from experience 😉 ). Fix some mypy errors (like the fact that in add_var the variable type could actually have been None as opposed to our previous declaration). https://bugs.python.org/issue40334
