That was on the mailing list:

https://groups.yahoo.com/neo/groups/forth200x/conversations/messages/1190

Essentially, a recognizer would consist of the conversion part (which we 
already have now separated in the recognizer word), and two different 
actions: the "literal-like" which puts the data into a definition, and the 
"final-action", which does something on the literal (if any - if it's 
completely literal-like, final-action is a no-op).

That pattern works for literals and also for the to-recognizer, where the 
final action is just ! (however, which ! depends on the data type of the 
value... and the literal-like does so, too, so it's not that simple).

What could be helpful is a table creator for literal-like recognizer, which 
takes the single action needed there (put the literal into the dictionary), 
and creates the three table entries for interpretation (nothing), 
compilation (just that "put the literal into the table"), and postponing 
(put the literal in the dictionary and then append the literal-like action).  
That could help people to write literal recognizers.  But that would be an 
additional feature, not a replacement.
