nmm, you coined 'chselect' in your original mail and Julien liked it as
well, so maybe we should just go with that. I now pushed the initial
implementation (as chselect) to git and also made a snapshot tarball:

Let me know how/if it works for you. We can still change the name, but
let's at least start with chselect. :)

I kind of like this as well. Mapping is general enough and fairly
descriptive.

And this as well -- chpick is really close to chselect (both seem
fairly intuitive).

We could reserve this for "randomize chain channels" operator. :)
