FYI, we (logilab) are curently working on providing a compatibility layer 
between _ast and compiler to get pylint working on py3k, py >= 2.6 and py <= 
2.5. There are some tree structure incompatibility between them which makes 
the thing not trivial but I hope we'll get somewhere soon. Of course any help 
is welcome :)
