The Go code parsing libraries are quite good though. Not sure what else you could want re. code generation.

Basically macros, like in Rust, not like in C. Rust can do stuff like the serde serialization library while Go has to rely on reflection with its obvious performance drawbacks.

Go could do something similar if you're willing to run `go generate` as part of your build process. For most Go applications, the reflection overhead is a fine price to pay for convenience, just like GC is a fine price to pay for not having to deal with the borrow checker. Obviously, these tradeoffs don't hold for all programs, but Go has definitely found a niche.

I'm not sure what you're arguing with. I know these things. I'm still missing the ability to have efficient serialization (as one example) easily. It matters.
