Description Keith Miller 2016-01-04 11:13:16 PST 
In general, when subclassing there is no way to know what the prototype of the created object is statically, as the new.target may change on each call. It is possible, however, if we inline to the construction site (i.e. the "new <function name>(...)" in JS) because then we might know the new.target statically.
