Programming Font and Syntax Highlighting Test/Sample Text

Question

What is the best text-block to use to test out programming fonts and syntax highlighting?

Answer 1

For lack of a better answer here is what I have so far:

void Il1egal0O(int null){
    switch(1|I[i]){ 
    case check_tab break;
    }
    return false;
}

Answer 2

The block needs to contain one of each element (one keyword, various symbols, etc) and the String Il1egal0O.

It must be simple to distinguish "capital i" from "lower case L" and "O" (letter o) from "0" (number zero).

Answer 3

I would suggest some code you work with each day - different programs, files etc.
