0f902bf2 - Provide better error hint when `UndefVarError` results from name clashes (#53469)

Provide better error hint when `UndefVarError` results from name clashes (#53469) We can detect this since we set the `usingfailed` bit when the clash occurs (to avoid printing the `WARNING` multiple times). In this case, typos or missing imports (the current message) isn't quite as clear as it could be, because in fact the name is probably spelled totally right, it's just that there is a missing explicit import or the name should be qualified. This code will stop working if we change the flags in `Core.Binding`, but the test I added should catch that. However if REPL is supposed to be independent of Base and not depend on internals there, there could be an issue. In that case we should probably add an API to Base to inspect this `usingfailed` bit so we can use it in the REPL. --------- Co-authored-by: Jameson Nash <vtjnash@gmail.com> Co-authored-by: Alex Arslan <ararslan@comcast.net>
