Isn't that enough?  What we have had has led us to having S", which is
implemented in some systems as a STATE-smart word (with problems in
corner cases), and in VFX to a solution with problems in other corner
cases.  By switching to a string recognizer we can replace S", and
eventually get rid of a bunch of STATE-smart words.

Another example is dates: We often hear from Forth, Inc., how their
Forth systems allow you to input dates by supporting /, -, and . as
double number indicators.  Let's see how this works out:

9.5.2017 cr d. \ customary in Austria                            
09.05.2017 cr d. \ alternative
2017-05-09 cr d. \ ISO format
05/09/2017 cr d. \ customary in the USA

This produces 4 different numbers for the same date, and what's worse,
different dates can produce the same number.  By contrast, if we have
a date recognizer (or one for each format), it can use the separator
to decide in which format the date is in, deal with the leading zeros
problem, and produce a result in a common representation (e.g., the
modified Julian Day number).  If you are so inclined, you could even
have a date recognizer that understands "9May2017".

I think you can think of various other recognizers for
application-specific data.

Getting back to the issue of STATE-smart words, another word that is
widely implemented as STATE-smart is TO.  You can have a recognizer
that replaces it.  You could even have that recognizer actually
recognize

TO word

But that might be confusing (TO looks too much like a word of its
own), so Gforth has a recognizer that recognizes ->word.

Another way to avoid the problem of STATE-smartness has been taken in
the pair ' ['].  That has the disadvantage that you cannot copy it
between compiled and interpreted code.  If you have a recognizer that
recognizes '<word>, you get rid of that problem.  Unfortunately there
exist words with a name starting with "'", and I think even pairs of
words, onbe with ' and one without, so it's probably better to use a
different pattern for a recognizer that produces the xt.

The scope recognizer is another example.  Instead of writing

also voc bla previous

you can write voc:bla.

Another recognizer (one that has been used for quite some time in VFX,
implemented in a VFX-specific way) is the dot-parser.  It allows to
access fields of objects, e.g., "myline.end", can be used with a class
name in a way similar to the scope recognizer, e.g., "point.x", and
also supports doing that to several levels, e.g., "myline.end.x".
