If you create a module using ``ast.Module([])``, then ``body`` attribute will be an ``_ast.astlist`` object. Try to extend this with anything. You'll get a traceback such as the attached.

I confirm still fails in 2.7.2a1, but it's not immutable as I expected: one may append, just not extend. Why isn't this simply a PyList (as in CPython)?
