Rust's impl are not highlighted quite correctly.

I noticed this earlier today, but my regex skills are not up to solving it on my own:

For the first impl, the type should be identified (as it is when following struct). For the second, both type (MyObject) and trait (Clone) should be identified, and "for" should not be confused as the control structure keyword for.

You're right. This is because the rule that matches impl statements is pretty basic right now. It's hard to match all cases because of the generic parameters. I tried a few times but didn't find a good solution either yet.
