We always had such things but I never advertise their usage.

Well, good luck with that as it will never be robust (apart from 
possible performance issues) ... make sure you also parse macros and 
included styles and everything that can contain some nested funny

interference with other preprocessing etc etc users are on their own i 
guess.)
