Yes.  I was thinking of the case where we wanted it to return something
useful which could be bound to the name "foo".  I suppose if you've had too
much caffeine you could dream up a case where w1() returns an AST based on
the original foo and w2() does something with it to cook up a new object,
but I suspect that would be pretty rare.
