[issue17430] missed peephole optimization

[Antoine Pitrou]

Antoine Pitrou added the comment:

The migration to an AST optimizer is a bit of a pie-in-the-sky project. Functionally, it doesn't have many benefits since the scope of legal static optimizations in Python is very narrow (due to the dynamic nature of the language). Therefore, the main benefit it would bring would be (presumably) easier maintenance.
