Method group natural type improvements

  • Proposed
  • Prototype: Started
  • Implementation: Started
  • Specification: Not Started

Summary

The proposal is that the natural/weak type of a method group should be determined by looking scope-by-scope and pruning inapplicable candidates as soon as possible, instead of considering all scopes at once and letting those inapplicable candidates fail the determination process.

Motivation

The motivation for the scope-by-scope approach is to prepare a better foundation for the extension types work.
The motivation for the early pruning approach is to better align with the principle used in overload resolution.

Detailed design
