--- | This class allows us to match client structure with client functions
--- produced with 'client' without explicit pattern-matching.
---
--- The client structure needs a 'Generics.SOP.Generic' instance.
---
--- Example:
---
--- > type API
--- >     = "foo" :> Capture "x" Int :> Get '[JSON] Int
--- >  :<|> "bar" :> QueryParam "a" Char :> QueryParam "b" String :> Post '[JSON] [Int]
--- >  :<|> Capture "nested" Int :> NestedAPI
--- >
--- > type NestedAPI
--- >     = Get '[JSON] String
--- >  :<|> "baz" :> QueryParam "c" Char :> Post '[JSON] ()
--- >
--- > data APIClient = APIClient
--- >   { getFoo         :: Int -> ClientM Int
--- >   , postBar        :: Maybe Char -> Maybe String -> ClientM [Int]
--- >   , mkNestedClient :: Int -> NestedClient
--- >   } deriving GHC.Generic
--- >
--- > instance Generics.SOP.Generic APIClient
--- > instance (Client API ~ client) => ClientLike client APIClient
--- >
--- > data NestedClient = NestedClient
--- >  { getString :: ClientM String
--- >  , postBaz   :: Maybe Char -> ClientM ()
--- >  } deriving GHC.Generic
--- >
--- > instance Generics.SOP.Generic NestedClient
--- > instance (Client NestedAPI ~ client) => ClientLike client NestedClient
--- >
--- > mkAPIClient :: APIClient
--- > mkAPIClient = mkClient (client (Proxy :: Proxy API))
---
--- By default, left-nested alternatives are expanded:
---
--- > type API1
--- >     = "foo" :> Capture "x" Int :> Get '[JSON] Int
--- >  :<|> "bar" :> QueryParam "a" Char :> Post '[JSON] String
--- >
--- > type API2
--- >     = "baz" :> QueryParam "c" Char :> Post '[JSON] ()
--- >
--- > type API = API1 :<|> API2
--- >
--- > data APIClient = APIClient
--- >   { getFoo  :: Int -> ClientM Int
--- >   , postBar :: Maybe Char -> ClientM String
--- >   , postBaz :: Maybe Char -> ClientM ()
--- >   } deriving GHC.Generic
--- >
--- > instance Generics.SOP.Generic APIClient
--- > instance (Client API ~ client) => ClientLike client APIClient
--- >
--- > mkAPIClient :: APIClient
--- > mkAPIClient = mkClient (client (Proxy :: Proxy API))
---
--- If you want to define client for @API1@ as a separate data structure,
--- you can use 'genericMkClientP':
---
--- > data APIClient1 = APIClient1
--- >   { getFoo  :: Int -> ClientM Int
