Object method documentation.

Right now, in the manual, there's no way to distinguish between static and concrete methods. Take the DateTime class, for instance. DateTime::createFromFormat is a static method, and in the navigation, table of contents, etc. it's referred to as DateTime::createFromFormat; however, DateTime::format is a concrete method and is also referred to the same way, so at a glance, there's no distinction between the two. Would it be possible to change the formatting slightly to add a distinction? Perhaps concrete methods could look like DateTime->format instead, as that would have some resemblance to how they'd be used in actual source code? Thanks, Eddie
