A lot of tools that work with Python source code use ast - so even 
though other implementations may not use the same ast "under the hood" 
they will probably at least *want* to provide a compatible 
implementation. IronPython is in that boat too (although I don't know if 
we *have* a compatible implementation yet - we certainly feel like we 
*should* have one).

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
