Or use:

	string str = ...;
	for (size_t i=0; i < str.length; i++) {
		/* do something with str[i] */
	}

I think this is the correct approach. Always err on the side of correct
and/or safe, but give the programmer the option of getting under the

A linguistics professor was lecturing to his class one day.
"In English," he said, "A double negative forms a positive. In some
languages, though, such as Russian, a double negative is still a
negative. However, there is no language wherein a double positive can
form a negative."
A voice from the back of the room piped up, "Yeah, yeah."
