Yes, matching regular expressions is easy, if you don't care about speed or features. Like, being able to match a literal dot or asterisk. Or char classes, or getting case insensitivity right (like the German ß that matches SS, so case folding needs not to preserve string length). Still nice to see that it can be done in so few lines.
