I'm using StringScanner (strscan).  It is NOT a lexer generator,
but it is sufficient for me (including speed).

For real example of Racc, refer TMail or RDtool.

  TMail (uses #yylex.  The lexer is written in Ruby and C)
  http://raa.ruby-lang.org/list.rhtml?name=tmail

  RDtool (uses #do_parse and #next_token.
  The lexer is written in Ruby using strscan)
  http://raa.ruby-lang.org/list.rhtml?name=rdtool
