Order is significant because of the shell. If you commonly use a program with option --foo, then you often decide to make an alias for the program that includes that option. If order is significant, then you can call the alias and add the --no-foo option to get a different effect without have to go around your shell alias. Some programs like 'less' even allow you to put options into an environment variable, then let command line options override the variable. -Lee
