Hi all,
 
Can somebody direct me to a part/facility inside the Spirit library to do the following:
 
I need to pre-parce a boolean expression (once) and save it somewhere.  Then I need to evaluate this expression (many times, performance important) based on different values of tokens.
 
Will Spirit.Classic do?  Or do I need to use any of the newer libraries inside Spirit?
 
Thanks for any help.
 
Arkadiy
