flex: boolean (optional: true ==> flex-like lexing behaviour where the rules are tested exhaustively to find the longest match)\n

the parseError function receives a \'hash\' object with these members for lexer and parser errors: {\n
text: (matched text)\n
token: (the produced terminal token, if any)\n
line: (yylineno)\n
}\n
while parser (grammar) errors will also provide these members, i.e. parser errors deliver a superset of attributes: {\n
loc: (yylloc)\n
expected: (string describing the set of expected tokens)\n
recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)\n
