I kind of like this idea. Simple, obvious, and leads
to clear code:

	a.dot(b).dot(c)

or in another multiplication order,

	a.dot(b.dot(c))

And here's an implementation:

	http://github.com/pv/numpy-work/commit/414429ce0bb0c4b7e780c4078c5ff71c113050b6

I think I'm going to apply this, unless someone complains, as I
don't see any downsides (except maybe adding one more to the
huge list of methods ndarray already has).

Cheers,
Pauli
