Hi Alexander,
The "primitive registration system" is a little more involved than
PRIMITIVE: but we defined that as syntax so we could grep and keep track of
our primitives better and as a placeholder for some future cleanup.
When you make a new "primitive", it needs several things including this in
Factor (which we hope PRIMITIVE: will replace someday):
* core/bootstrap/primitives.factor (make-primitive)
* basis/stack-checker/known-words/known-words.factor (define-primitive)
And this in the VM:
* vm/vm.hpp (defined)
* vm/primities.hpp (exported)
* vm/*.cpp (implemented)
We have an issue for improving this, although we won't likely get to it
right away:

Thanks,
John.
