Search and display the most likely result.  SEE in bigForth is not always 
100% accurate, either.  Example: If you have DUP +, you can optimize that to 
2*.  A SEE that reports 2* would be fine for me.  Or when you do constant 
folding, just display the results (e.g. 1 2 + would result in 3).

How easy that is depends on how many optimizations you do.

Sure, but that's a different purpose.

I've other words to see the actual code.  SEE tries to reconstruct the 
source code.
