The 2to3 syntax tree is probably two low-level for that. It's good for simple isolated transformations like print, but not so much for the larger scale analysis that a lint tool would require. In addition, we'd have to write some sort of symtable analyzer. High level AST is much nicer to work with that.

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 :)
