Using ifs on the arms is a nice way of doing this :+1:

We'll eventually be able to just

match input {
    const { A | B } => ...,
    _ => ...,
}

once the following RFC is implemented:

Ah yes that will be nice. I suppose at that point this crate will only be useful if you have non-const expressions. Don't know how common that is.
