Makes sense, most likely that integers will be enough for kernel-use
too, that's what was available from C so far :)

Indeed I don't think the security issues are an immediate concern, as
scripts are likely to be part of the base system for now and installed
by the superuser, and as you said, dynamic kernel modules are already
more dangerous.

Thanks for your answers, and for working on this, BTW.
