[Alain] Long live APL!!! It makes very compact and rigorous programs. It
used to be my pet language when I was a student. Alas, too many people find
it cryptic. Personally I am all in favour of pictograms everywhere, as far
as possible (it avoids many linguistic problems, in particular in
multilingual environments -- such as airports). It requires, unfortunately,
a lot of education, as most of them, beyond a certain number of elementary
ones, are not obvious nor intuitive at all. But it is worth the effort,
this kind of education. Btw Canada (in fact Michel Cartier, Université du
Québec à Montréal) once has proposed an iconic grammar, but it has not come
of age yet (the relevant ISO committee found it interesting but did not go
forward in implementing it in user interface standards).
