patch 9.0.1741: No type checking in interfaces Commit: https://github.com/vim/vim/commit/c5d2744c045f9ad058cbc799f2434d90a6d83516 Author: LemonBoy <thatlemon@gmail.com> Date: Sat Aug 19 13:02:35 2023 +0200 patch 9.0.1741: No type checking in interfaces Problem: No type checking in interfaces Solution: Implement member type check in vim9 interfaces Most of the code is a small refactoring to allow the use of a where_T for signaling the type mismatch, the type checking itself is pretty simple. Improve where_T error reports Let the caller explicitly define the kind of location it's referring to and free the WT_ARGUMENT enum from its catch-all role. Implement type checking for interface methods Follows closely the logic used for type-checking the members. closes: #12844 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: LemonBoy <thatlemon@gmail.com>
