I think it would be nice. We usually founder on trying to provide a
facility which can replace the builtin printf support, since printf is
very complicated.
I kind of liked this idea:
http://gcc.gnu.org/ml/gcc-patches/2005-07/msg00797.html
but of course it was insane.
And then there was this idea, which I think was almost workable:
http://gcc.gnu.org/ml/gcc/2005-08/msg00469.html
But nobody really liked it.
So you need to find something which is on the one hand very simple and
on the other hand able to support the complexity which people need in
practice.
