Stroustrup means using YACC or Bison I think, the programms that
generate LALR(1) parser and, consequently, demand input grammar must
be LALR(1). It is known C++ grammar is not LALR(k) for any k. So,
Stroustrup spent much time trying to write LALR grammar for C++. For
the moment there is GLR parser as the next generation LALR parsers,
which makes writing C++ frot-end fast and simple time spending.
