I guess this is close to the point where our views diverge.

In PLT Scheme, we spend lots of time implementing macro-based language
variants (e.g., HtDP Beginner Scheme) and constructs (e.g., classes and
mixins and traits). So, extra time spent on the compiler does not seem
like time lost to other optimizations, but time saved from fighting
macro-staging problems.

In any case, I'm still willing to standardize on the phaseless model,
even though I think it's flawed.
