I didn't come up with the concept (that's from MPE and Stephen Pelc).  I'm 
not even sure if I used that term intentional or accidently; it started out 
as synonym.

MPE just hides it inside their glossary entry of COMPILE,:

defer Compile, \ xt --                               6.2.0945
Compile the word specified by xt into the current definition.

and has a single sentence that shows the possibility of using SET-COMPILER 
to replace STATE-smart words:

"State-smart words (considered "evil" by some) can be be avoided using set-
compiler and interp>."

(page 202 in my copy).  It's pretty obvious that this sentence is a 
consequence of your "State - why is evil and how to exorcise it" paper, and 
from the context of VFX's compiler (which is a lot about optimizing), you 
can suppose it relates to usage 2 of STATE-smart words:

http://www.complang.tuwien.ac.at/anton/euroforth/ef98/ertl98.pdf

This paper contains two usages of STATE-smart words (both problematic), and 
two different solutions: dual-xt for the parsing words, and intelligent 
compile, for optimization.

We changed Gforth from STATE-smart to dual-xt, experiencing little problems.  
MPE changed from STATE-smart to "smart compile," (i.e. using solution 2 for 
problem 1, too), and experienced little problems.  Why?

Because STATE-smart words have apparently more problems, especially all the 
corner cases where dual-xt and smart compile, differ, STATE-smart is even 
worse.
