Not so. This is a very simple thing I posted above. In such a simple case, the other cases would be handled differently. You'd need strings bigger than 100 chars before len would be slower and then for all the people who say m. is not important, the differences are not important enough to suggest that doing the conditional check in the loop is better most of the time.
