Maybe, Idk who that appeals to.. But Go lacks the even most trivial of array / slice manipulation functions. Is this loop an index() or apply() or filter() or count() or sum() or wutt? Don't even talk about generic data structures. To be fair, Go authors are pretty smart having created something more usable than C while not even seriously looking at how things are done in other languages.
