Task? Flow?

[awb99]

It would be great to have a
(defn task? [v] that returns true if it is a missionary task, otherwise false.

Same would be useful for flow.

Why?

I want to write a value to the browser dom.
In order to use different paths to render a dom value or a task that returns eventually a dom value I need some way to determine what kind of value I have.

Perhaps such information can be added as meta data?

Thanks.
