That is not manually memory management though, and it also comes with its own set of issues, like everyone that was tried to write GUIs or games in Rust is painfully aware of.
That's true. The comment by mlwiese up-thread, that I responded to, praised Go's low GC latency without mentioning the heavy memory and throughput overheads that come with it. I felt it worth pointing out the lack of a free lunch there; I think a lot of casual Go observers and users aren't aware of it.
Agreed, although if Go had proper support for explicit value types (instead of relying in escape analysis) and generics, like e.g. D, Nim, that could be improved.
