Howdy!

Of course.  What I was suggesting was to push “my” series first, then
rebase “yours” on top of it without the kmod bits since we can now do
without it.

How does that sound?

(I understand it’s somewhat unfair.  I wanted to submit my part before
you started working on the rest, but you’re so fast that I just can’t
keep up.  ;-))

Honestly I feel it’ll be easier to deal with a small pure-Scheme
implementation.
