That's true, Tango's parser is simple and well done, and it's using 
final (thus non-virtual) functions. It being object-oriented only has a 
negligeable impact when you instanciate the parser.

I'm not writing my own parser because of any flaw in the Tango parser. 
I'm aiming at providing some features not found in Tango (like optional 
checking for well-formness) without compromizing on performance when 
you don't need them (templates are good for that). I'll also try to 
outperform Tango with callback parsing, but I expect it can only be 
done by a tiny margin, if at all.
