Not giving a technical description since everything is there perfectly in the linked answer. To merely replicate the gist of it as an answer here, it would look like:

A                       //generic,     bound,  open,   constructed
A                     //generic,     bound,  open,   constructed
A                   //generic,     bound,  closed, constructed
A<,> (used like typeof(A<,>)) //generic,     unbound
