I don't care about the snake language.

frankly all that's missing is a "safe" accessor library as Steve has
promised will appear.

that library really needs to be a proper shared library and not come
from/with the kernel package, so that distributions can independently
package it properly.
(and this obviously needs to at least look at the things that the
systemd guys pointed us at at the kernel summit)

I'm not interested if the code for a library is somewhere deep in the
kernel source code, not installed by default in distros (or tied in with
loads of other mess) and/or uses the kernel makefiles/etc like perf does.
