The problem is that the ruby grammar is injected into your scope, this 
means that whenever the ruby grammar opens a new scope, the entire ruby 
grammar will also be injected into that scope, since the scope selector 
used for the injection still match.

I think you can inject into `meta.embedded_ruby $` and it will only 
inject into the root of this sub-scope (due to the `$`) — during 
injection, the attribute scopes are currently ignored, which is why the 
tail anchor works.
