#[pyclass] enums do not retain identity when converted from Rust to Python

[alex]

Simple reproducer:

#[pyo3::prelude::pyclass]
enum Foo {
    E1,
    E2,
}

#[pyo3::prelude::pyfunction
pub fn get_foo() -> Foo {
    Foo::E1
}

if you wire this up, and call it from Python, you'll find that get_foo() is get_foo() is False.

It would be useful if these always had the same identity, as this would more closely mirror the pure python enum module's behavior.

Is this possibly a duplicate of #3059? (With the resolution #3061 being underway.)

Yuuuup. Sorry about the news. Apparently 9am is too early for me to know how to search.
