Because Rust is not a GC language. I should have perhaps explained that better. My round about point mentioning Rust was that instead of putting "*" all over the place you could just have types that represent such (pointers) or the opposite (ie value types) depending on what the language defaults to. I mean the pointer in some senses is effectively abstract wise Pointer<SomeType>. However I suppose this is difficult with out generics. That is I don't mind the explicitness of Rust because I guess I expect it just like C/C++ but I probably incorrectly expect it with Go lang. This is mostly because I come from a JVM background where I expect the VM to figure out what is more optimal and consequently also have very little experience using in/out parameters.
