Remember that, when you are skilled, you write a top-down parser right 
from the BNF grammar; the technique is to write 1 procedure for each BNF 
production, so there is a 1-1 correspondence between BNF and code.

The resulting parser is, from my experiece, very easily maintanable 
without the skills you need when you use lex/yacc like tools.
