the astng package from logilab's common library [1] extends compiler AST
nodes with a bunch of methods, including a as_string method on each node
allowing to regenerate a python source code from an ast (other methods
are mainly to ease navigation in the tree or to extract higher level
information from it). Currently it's implemented as a node's method
instead of using a visitor pattern or the like, but that would be easily
done.
