Client response body conversion to JSON

[freiden]

Hello,
My issue is more a question than a bug. I want to extend some behaviors of this gem and I stumbled into the implementation of the conversion of the client response body to JSON and I would like to understand this part line 18:

klass = Module.const_get("FHIR::#{resource_type}")

Why not pass to the #from_json method the klass objects from the callers and eventually fallback on retrieving it from the resource_type?

Thanks in advance.
