    StackToRegisterMappingCogit genAndDis: (Integer >> #benchFib)

I have concrete subclasses that implement different levels of

optimization:

    SimpleStackBasedCogit is the simplest code generator.

    StackToRegisterMappingCogit is the current production code

generator It defers pushing operands

    to the stack until necessary and implements a register-based

calling convention for low-arity sends.

...

    StackToRegisterMappingCogit is an experimental code generator

with support for counting

...

    conditional branches, intended to support adaptive optimization

Should StackToRegisterMappingCogit be duplicated twice there?

Oops, thanks Ben. I'll commit a fixed comment soon.
