Can I preserve a callback across multiple steps? about step HOT 2 CLOSED

There are several ways to do this.

(#1)
One would be to have your refine callback return a result object that contained both the person and the blurbs.

    { person: person, blurbs: refinedBlurbs }

This is probably the more correct method.

(#2)
You can also do

    this.person = person 

in the second step and then refer to this.person. I find that a bunch hackier though. It can be handy though if you're doing stuff in parallel with (I'm assuming) multiple blurbs.

(#3)
You can also run a 'parallel' process to your blurb refinement.
Then if you need a 'group' process for the blurb refinement you can also call step again inside of step

    var personCB = this.parallel();
    personCB(person);
    var firstStep = this;
    step(
      function () {
        //group blurb refinements
      },
      firstStep.parallel()
    )

from step.

In the new proposed API, there is a this.pass() function that passes values to the next step. Comment at #24
