Exception: Unhandled node type <class '_ast.NameConstant'>

Patch:

astutil.py:

    def visit_NameConstant(self, node):
        self._write(str(node.value))

and possibly:

visit_NameConstant = _clone

(not sure what is it)

Moved to milestone 0.9.

I'm pretty sure this is a duplicate of #582 (already fixed, just not released).

[hodgestar]

Agreed. Closing.
