One mention of ASIS and some mentions of recursive descent parsers
have been made. I shall state advice for you in a more direct
manner. Do not write anything based on Lex and YACC. They are for
bottom-up designs. Learn how to do top-down parsing or otherwise be
damned to never write an unbuggy parser.
