It automatically compiles the lexer in optimized mode, writing to ``lextab`` in the same directory as the calling file. This function is thread-safe. The returned lexer is *not* thread-safe, but if it is used exclusively with a single parser returned by :func:`yacc` then it will be safe. It is only intended to work with lexers defined within the calling function, rather than at class or module scope.

It automatically compiles the parser in optimized mode, writing to ``tabmodule`` in the same directory as the calling file. This function is thread-safe, and the returned parser is also thread-safe, provided that it does not share a lexer with any other parser.
