As of PHP 5 $this is a very special variable, I couldn't find anything in the docs about it's limitations, so I mark it as a doc bug.

Related to the original report: I'm also not seeing a hint that you can't assign any value to $this in the docs (not even outside a class)

Partially done, I'll add a note about $this not being modifiable as well.
