Robert,
I'm working on k = 1, as suggested by Josh Berkus and with whom many
people agree. It is a simple default behaviour that will be easy to
test.
Greg's proposal to implement other alternatives via a function is simply
a restatement of what I had already proposed: we should have a plugin to
provide alternate behaviours. We can add the plugin API later once we
have a stable committed version. I am happy to do that, just as I
originally proposed.
I don't believe it will be helpful to attempt to implement something
more complex until we have the basic version.
