LPEG filtering

[Mark Hamburg <mark_hamburg@...>]

Is it possible as part of the semantic action/capture logic in LPEG to  
attach filter functions? For example, could I match a number using the  
LPEG patterns and then range check it with a Lua function? Or would I  
need to do that work after the pattern match finishes?

I just read the LPEG paper and I don't recall seeing anything about  
this sort of functionality.
