I'm sorry, but that is such an incredibly subjective difference that I can't do anything with it. String literals and numeric literals are syntax too, even though they are values. A keyword, or reserved word, is simply something that looks like an identifier but is converted into a different token (by the lexer or by something sitting between the lexer and the parse) before the parser sees it. Also note that null is a keyword in Java. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
