Answer 1

type typeRegistry = map[string]Typ

Is a type alias. You cannot define methods on aliases (only on the original type--but in this case map[string]Typ cannot have methods on it, so you're out of luck).

What you probably want is to create a custom type, not an alias:

type typeRegistry map[string]Typ

Then your methods will work.
