[x] You didn't read Mitch Bradley's message on the Forth200x mailing 
list.  Mitch describes clearly for what it was envisioned, and you still 
ignore this.

I think this discussion with you leads nowhere.

If you want "postpone literal postpone execute", do so.  That's not what 
COMPILE, is meant for - read the mentioned mail from Mitch Bradley, the 
author of the COMPILE, proposal in Forth-94.  COMPILE, is the API to 
compile non-immediate words referenced by xts.  The reason why it is 
specified as it is is that in classical Forth implementations words have 
either a default compilation semantics *or* they are immediate, in which 
case their compilation semantics is invoked by EXECUTE.  In a classical 
threaded code system, you use , to do the job of COMPILE,.  COMPILE,s 
job is information hiding, and the standard does not mandate that words 
with special compilation semantics have to be immediate.  That's the 
purpose of declaring semantics instead of flagging words with "I" and 
"C".  And no, we don't have to invent a new word to get the compilation 
semantics of xts from non-immediate words, Mitch Bradley already did: it 
is called COMPILE,.

The idea that a word called *COMPILE,* is there to explicitly access 
*interpretation* semantics is mind-boggling.  Just because someone 
rushed in a late proposal, you say we should stick to its mistakes?  For 
operations on words with special compilation semantics, which are really 
rare, and a user can't define them himself by using standard words?

According to your argument, access to the interpretation semantics of S" 
(which is easily done by ['] S" EXECUTE, so no extra words necessary) 
using COMPILE, is more important than the ability to write your own text 
interpreter (because monotoken systems should invent a new word for 
this).  I think you should consider to adjust your priorities.
