The goals here are four-fold:
- provide cleaner internal abstractions
- avoid IR bloat from extra bitcasts
- avoid recomputing function-type lowering information
- allow more information to be propagated from the function
access site (e.g. class_method) to the call site
Use this framework immediately for class and protocol methods.
