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. Randy Brukardt
