     Might there be a better forum for ANS discussions? comp.lang.forth
comes to mind. There was an ANS-FORTH mailing list at one point and you
might ask around among the committee members from the last go-around what
discussions are under way. This deserves a wider, ANS-focused audience. If
FORML gets restarted (in Reno or Las Vegas?) that would be a good forum.
     As long as we are off-topic, another point you might want to keep in
mind is that the standard CODIFIES EXISTING PRACTICE.
This is from the charter and seems to have been ignored at times even by the
last round of standardizers
