If you want a one-shot lookup like <wordlist>::, that recognizer might push 
a special one-shot recognizer on the top of the recognizer stack (or replace 
the complete stack and save it somewhere else), which looks up the specified 
wordlist, and removes itself from the recognizer stack (restore the original 
stack).

That thing would be difficult with POSTPONE, but would work fine within ]]
