Despite misgivings about the language as a whole, I think that Go does interfaces extremely well, and made the right choice to discard "implementation inheritance". That said, in my time with obj-c I never really encountered the problem of fragile base-classes - protocols and categories gave us just about everything we needed. (the foundation classes use implementation inheritance extensively, but we don't typically modify those too often :) )
