I didn't profile, but apart from the time-complexity that is 
inherent to straight forward recursive descent parsers like 
Pegged (improved by memoization), my impression is that Pegged's 
main performance problem is due to a very high constant: it is 
concatenating strings, all the time. A LOT of strings, and a LOT 
of concatenations. Almost all of them are discarded, of course. 
Finding a way to do the same without string concatenation would 
have a big impact.
