Well, some of us have our own Ada compilers (Janus/Ada in my case), and I
certainly hope that you are not advocating the elimination of all other Ada
technology. I can't think of anything more certain to kill Ada than to have
only one source for compilers - that would mean that one size would have to
fit all, and that is unlikely to be true.

Certainly, Janus/Ada is not going to compete in every environment with GNAT
(it's certainly not suitable for hard real-time work, for instance), but it
keeps alive techniques that have disappeared elsewhere: real generic code
sharing, discontiguous objects (no allocate-the-max bs here), and so on.

I wouldn't suggest that anyone start from scratch, though, because I've
spent about 17 years of my life working on Janus/Ada (along with a number of
other people), and that sort of investment is not something to undertake for
most humans. And a compiler for the "easy" subset of Ada is unlikely to be
interesting.
