To everyone searching the page for "generics", they're still not there.
If you follow Golang development, one of the uncanny things about it is how they really seem to nail the release schedule. They say what they're going to do. They say when they're going to be done. Then they do it, and announce their completion.
I think you can safely assume you'll know a ways ahead of time if Golang is suddenly going to become acceptable to people who require parameterized types to adopt a new language.
I have decided to shut up about them.
Regardless of having generics or not, every line of Go code is a line less of C or C++ with Cisms code, so in a way it is already an improvement.
