I checked again. The thing is that in the compiler overload handling is
done inside htypechk.tcallcandidates. Your patch weakens/changes that. So
you'll have to completely rethink your solution to fit it into
tcallcandidates (that should for example collect all suitable generics in
addition to the non-generic ones (if any)).
