Yes, you are onto something there, something I didn't mention. When building a plugin (using -buildmode=plugin, see https://golang.org/pkg/plugin), the Go compiler does in fact generate a table mapping names to types for the names defined in the main package. That table is used by programs that load the plugin in order to get the correct types. But that only exists for plugins, it's not a general approach.
