That would still require dynamic dispatch of some kind.

But it wouldn’t require a heap allocation.

Where is the proxy implementation going to go if not the heap?

Until then, we use `Either` (https://stackoverflow.com/a/50204370/155423)

Tangentially, do you know why Rust never included an Either type? We have Result, which is great, but Either is useful for more things than errors (though that seems to be it's main use).

We had it for a long time, as well as result, and literally no code used it, so we took it out.

There’s a crate on crates.io for it if you want to use it for something.
