This isn't the answer I wanted, but it's a good answer. Thank you

You’re welcome. (I imagine that you’d get the same version conflict situation with your idea btw: std::2018::Option is not the same type as std::2021::Option.)

[littlestymaar]

Even if std::2018 is just doing: `pub use std::2021::Option`?

[steveklabnik]

Ehh you're right, actually.

I still think you run into other issues, though.
