This is not part of my de-emphasizing scheme. Ultimately what I am
doing will need a scheme interface. I will leave it to one of the
scheme lovers to do that. People like coding gnetlist backends in
scheme and I am not going to fight that. I never said I wanted to kill
off use of Scheme just have an alternative but that is something I can
wait on until another day. Look at how contentious just doing this has
been, could you imagine the uproar if I tried to do something as
massive as a plugin interface at the same time? I wanted to do this
project but honestly I did not originally intend on starting it right
now. I saw changes coming to the netlisting mechanism and got
concerned at the effect they would have on the long term viability of
the idea.

I also consider having a subset of the C functions visible in Scheme
to be a feature not a limitation. A lot of that stuff should not be
available because it is low level code that out of it's native context
is just clutter. Does scheme really need to be playing with all the X
and other rendering nitty gritty? IMHO the answer is no.
