While having generics as part of the language and doing the code-gen in the
compiler has definite advantages (ease of use and potentially better
optimization of the generated code), doing it as a separate tool *also* has
advantages. For example, this way no one is bound to whatever notion of
generics will eventually be built into the language. Because it *will* have
limitations and provide a trade-off. With separate tooling outside the
language, people can make their own tradeoff.
For example, yes, you can do template-like code generation at compile time.
But you could also box values in interface{} and have a tool that verifies
your desired notion of type-saftey statically. It's up to you - whatever
makes more sense for your use case.
Honestly, right now I'd prefer good and easy to use meta-programming tools
for go. If I can write my own type-checks or code-gen to be run on a go
build, it enables far more powerful tools than generics alone… (yes, it
also has drawbacks. I'm aware).
