I'm not sure if the author is being sarcastic or not. Nevermind. In Perl 6 one can use non-keyboard chars to represent stuff, like operators, etc. Ergo, you could define ANSI color codes as operators so the code could be color-dependant in theory. /funnymodeoff

I don't think it's sarcasm (well, I'm not too sure about the colors part). Pretty much every non-alphanumeric symbol has more than one meaning in a language like C++, which (IMHO) makes reading code slower than it could be. For instance, I would really like to have a proper arrow operator instead of "->" for C++ which wouldn't match visually with a "<" placed before in the same line.
