Oooh. My bad. Thank you! I honestly thought that wasn't possible at all. Today I learned.

However, it won't work for return values, right? Because e.g. `func (some something[T]) hi(b T) T` would return `any` and not whatever it was provided (`int` or `string` respectively).

Also, I don't think this can work well with types narrower/fancier than `any`, e.g. I had trouble figuring out how to deal with

    type IntOrString interface {
        int | string
    }
    
    type something[T IntOrString] int
