In selector resolution, struct field matching now precedes method matching. Before struct field matching could be skipped in case of a matching method, which is incorrect, as demontrated by _test/issue-1156.go. Field lookup has been fixed to operate on recursive structures. Concrete type values are derived when filling a receiver for interface methods. LookupBinField has been fixed to skip non struct values. LookupMethod has been fixed to iterate on interface values as well as concrete type values. Fixes #1156.
