I'm considering it as an option to deal with some of the builtin library complexity, so it would be used with a restricted set of known functions. I'm not planning on exposing this as a user facing feature. The resolver would be known trivial after link and optimize out most of the time, but needs a fallback where a global constructor will do just fine.
