Nicely done and long overdue, IMO.  Thank you.

Neon was using this in 1984.  So you're right, there is quite a
history.

Re: Confusing ) with } or whatever.  The compiler can help a lot.  For
example in Mops:

: test { a b -- )
  a b + . ;

Error # 245  ')' read when '}' expected
: test { a b -- )
                ^

Also, if seeing this is a problem then I suspect one is having problems
seeing other characters as well.  Either get proper gl*****, use a
larger/different font, or get a bigger screen, or any combination of
the above.  :-)


Re: FVALUE    We have had this in Mops for a long time and I would not
be without it.

Re: Prefix Operators    We have also had these in Mops (Neon?) and the
operators are quite smart in that they work on VALUES FVALUES
NamedInputs and Locals.  The operators include the equivalents of TO
+TO and -TO  ( actually in Mops it's -> "gazinta" ++> and -->, but I'm
not going to quibble).

Re: NamedInputs and Locals re-declared and re-entrance.   Egad.  The
"We don't need no steenkin' locals" crowd must be gasping.  I'm
certainly not anti-locals, but this would seem to be overdoing it.  I
gather that you are not proposing this.  But I see some discussion
about it.  It seems to me that any NamedInputs and locals should be
declared just once up front at the start of the definition.  For
clarity at least.  Of course if it is allowed I certainly don't have to
use it.  :-)

Regards and Good Luck.
