[issue29630] REPL tab-completion triggers code execution

[Francisco Demartino]

Francisco Demartino added the comment:

> There is no way to safely inspect any Python object without triggering some dunder functions like __getattr__, __getattribute__ or __dir__.

But somehow inspect.getattr_static can do it?

Why is it less useful? The only change is not executing property getters when showing completion options. It's removing a surprising code execution before the newline is received.

Should CPython keep backwards compatibility of this execution-on-completion at the REPL?
