The original comment was about how both debugging and generics are being implemented with code generation before runtime in Go and described this as "unusual." The response was that this precise technique is how generics are implemented in many languages already; in fact, CFront (the original C++ compiler) was entirely implemented as code generation on top of C. The response specifically discussed generics, not debugging, so I'm not sure why you thought it was talking about debugging.
