Pattern matching is great, but probably not if everything is pattern matching. Also I'm okay with XML as long as it doesn't power an urge to make everything XML

Pattern matching is great, but probably not if everything is pattern matching. Also I'm okay with XML as long as it doesn't power an urge to make everything XML and everything connected via the semantic web (lol). XSLT is a remnant of that urge and should have been a non-XML-based language. (The same criticism applies to, e.g. RDF vs. Notation3.)
