If such an extension mechanisms must be supported, I'd rather have the 
Lua API be extended with a runtime mechanism for registering function 
into a list of callbacks to call at specific well defined events, as 
compared with the existing macro definition mechanism.  This way 
separate extensions won't trample on each other.
