That's a good idea indeed if we ever intend to have other kinds of generic arguments (in particular, constant values like `length: Int`).

Even so, I wouldn't want to prohibit adding more protocol constraints in the where clause even if you can introduce all constaints of `T` at once as `T: protocol<A, B>`.
