>There are plenty of "proper implementations" of these collection classes. Your only criticism of them seems to be that they are not type safe. But it is trivial to implement a type safe wrapper around such containers, if you desire it. So the situation is perhaps a little cumbersome, but no worse than C.

"no worse than C" doesn't sound particularly enticing.

>The Go language and libraries, by contrast, are amazingly regular. This is not just my opinion, but the feedback that I receive consistently from Go programmers around the world.

Selection bias?
