By doing this, we will in most cases resolve the overloading the same way as if the callers and callees are host functions, therefore resolved the same way as in their expected environment. This will make sure: 1. we will not end up with no viable candidate 2. we will not have ambiguity, since we know it is resolvable in host compilation.


LMK when you have something. I can give it a spin internally.
