You can always post patches to the list. ;-) Also, as I said, I invite 
people like Andreas, Sebastian and David to review your patches. 
Especially refactoring patches should be easy to review.

Specifically, the fact that you changed behavior could have found by any 
other patch reviewer, with me only really being needed to explain why 
the current behavior is as it is.

I like the current idea of having the isl ast show to the user what will 
be code generated and would like to preserve this behavior if there are 
no strong reasons against it.
