If you have a chain of objects where a.foo -> b, b.foo-> c, etc,
use this to iterate over all objects in the chain. Iteration is
terminated by getattr(x, attr) is None.
Args:
obj: the starting object
attr: the name of the chaining attribute
Yields:
Each successive object in the chain.

S( s Returns true if node is in an environment where all that is required
of it is being iterable (ie, it doesn't matter if it returns a list
or an iterator).
