Working with resources

Etsy API supports ability to query data related to a certain entity, all within one request.

Currently, we can use the "include" parameter as an array of strings. However each of these strings is a name of an entity and there should be some restrictions / types what this array can accept.

Etsy API allows retrieving up to 3 nested associations with this syntax:
?includes=Association[(fieldname[,fieldname...])][:scope][:limit[:offset]][,Assocation...]

Research how other typed Etsy API wrappers have achieved this. If there are no examples find a good solution that allows easy creation of these queries. The query should be typed and it should also predict the exact result type.
