Sort of. In the mathematical space yes they can be defined without subjectivity. Outside of that space where the 15-second sound bite and attention-deficit disorder reign supreme, a space where Rebol needs to communicate - they are subjective. One aspect of that subjectivity is for example the Rebol send function. This function seems minimalist to many, yet those who know how to deconstruct that functionality will not consider it to be part of a minimalist set of functions. That's the feel I was trying to get at with the reference to Mathematical space and subjectivity. It depends on your context. ...

Ok that is something concrete, obvious and submittable to [feedback--rebol--com] :) Brett. Ps. Thanks for the other material I snipped from the post.
