Re: VALUE and TO implementation

What makes you think so?  Everything is normative that is not marked
as informative (the appendices).

- only compliance requirements, which do not
include TO. See standard section 5.

Sure, you can implement a Forth-94 or Forth-2012 system that
implements only the core wordset.  But if you implement TO and claim
that your system is a standard system, your implementation of TO must
behave as specified in the standard.  See chapter 3:

|No standard word provided by a system shall alter the system state in
|a way that changes the effect of execution of any other standard word
|except as provided in this standard.

Don't nail your own foot to the floor...

Of course, you are free to implement a non-standard system.
