Helper to make code using records of clients more readable. Can be mixed with (/:) for supplying arguments. Example: 
type Api = NamedRoutes RootApi

data RootApi mode = RootApi
{ subApi :: mode :- NamedRoutes SubApi
, …
} deriving Generic

data SubApi mode = SubApi
{ endpoint :: mode :- Get '[JSON] Person
, …
} deriving Generic

api :: Proxy API
api = Proxy

rootClient :: RootApi (AsClientT ClientM)
rootClient = client api

endpointClient :: ClientM Person
endpointClient = client // subApi // endpoint
