Subject Re: Ivy 2.5 and generics
Date Tue, 20 Jun 2017 12:06:15 GMT
I left out the generification of Filter, because NoFilter is a singleton.
I'll be leaving out attribute Maps (global or local), because their values
can be Strings or Matchers (this is where the story with IvyDE started, I
was not sure what to expect from one such Map).

Anything else that is pretty unambiguous can be generified just to clear
out the room. Once that is done, the remaining cases must be thoroughly
discussed. I added binary compatibility checks to stress the point that
generification does not break binary compatibility as long as erasures stay
the same.
