Most generic implementations are not Turing-complete, and looking at C++, this doesn't sound like a particularly tempting proposition.

And while I'm not particularly familiar with Go, I don't see how you can get a feature set equivalent to a simple implementation like Java's out of Go interfaces ("you can just cast" is not a good answer).

I'm probably missing the use case. What is the problem that you are thinking of, you can't solve with a Go interface?

Say, a generic container.
