A swagger schema looks like YAML with a finite set of types. I don't see why you'd need to use eval in that case when from one hand you already have the schema in a javascript object and the other hand a simple builder pattern would build your API directly from that schema. Absolutely no need for macros.

Generally speaking, because it would be very nice to have types without having to do offline code generation.
