Many coding standards, if not most, require to have meaningful variable names even for temp variables. $response = loadConfig() |> buildDic($$) |> getApp($$) |> getRouter($$) |> getDispatcher($$, $request) |> dispatchBusinessLogic($$, $request, new Response()) |> renderResponse($$) |> buildPsr7Response($$) |> emit($$); Nice, clean, readable and explicit. i.e. Don't have convert $x is return value from previous call in programmer's head. > I'm not sure if there is a ORM or database library out there which constructs SQL queries with non-oop calls, maybe you can give a real-world example.
