It is my impression that users of compilers are "ready" for the
following situation:
1) an optimizing compiler (like ocamlopt!) that produces good code
efficiently
2) a super-optimizing compiler that produces fantastic code, at whatever
cost.
Such a compiler would probably rapidly find a niche of fervent users.
