Simplicity of implementation also contributes to Go’s fast compile times, which is a different sort of performance. Trying to find a sweet spot between “slow” interpreted languages and “fast” compiled languages with long compile times (e.g. C++ template hell) is a worthy goal.
I think multi-profile compilations is much better - have a really fast debug build that hardly does any optimizations, and a release one that can take whatever amount of time but will be really optimized.
