A version of auto with the functionality of waterfall would be nice.

So a task with two dependencies would get two data parameters.

Apologies if this already exists, but the documentation seems to suggest it doesn't.

Good question.

One could use a closure to make intermediate results available to all functions defined within auto. However having the option to pass them around explicitly along with the callbacks would be nice.

Implemented it. Pull request #12.

This seems to have been implemented since the issue was opened, so it should be closed.
