Here is a related ticket that proposes a more explicit alternative: adding a ``dot`` method to ndarray. http://projects.scipy.org/numpy/ticket/1456

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/414429ce0bb0c4b7e780c4078c5ff71c11305...

I think I'm going to apply this, unless someone complains,

I have a big one: NO DOCSTRING!!! We're just perpetuating the errors of the past people! Very discouraging!

as I don't see any downsides (except maybe adding one more to the huge list of methods ndarray already has).
