/// @assertion We do not allow implicit instantiation of callable objects. Given
/// e<typeArgs> where e has a static type which is a class with a generic call
/// method, we do not implicitly convert this to e.call<typeArgs>, like we would
/// for a call like e<typeArgs>(args). You cannot type-instantiate function
/// values, only call them, and here we treat "callable objects" like function
/// values. You can write e.call<typeArgs> and treat call as a normal generic
/// instance method.
///
/// @description Checks that in case of e.call<typeArgs> call  is treated as a
/// normal generic instance method.
