Overview

A reference to a union hoisted into the shared unions module (a named shared fragment spread as a whole union field): the query references ::Type and dispatches through .from_h, where is the alias the query module gives GraphQLUnions::. The type family lives once in the shared module, so the same union across queries is one Ruby type — nested is nil, nothing is emitted here.
