I don't think you can, not in the current implementation of inner classes, 
at least.  There's probably a way to hack the inner class reference to get 
at the outer class reference, but it's probably not recommended ;)  I agree 
that it'd be very nice to have.  It's kind of like not being able to get the 
context pointer of delegates (which, according to Walter, are similar to how 
inner classes are implemented).
