I am *very* much in favour of improving the compiler so that it can be helpful, but only by giving appropriate hints, as Ralf pointed out already. Since I doubt that we will be able to exclude the possibility of having two different coercion paths, however, I want that code in the library is unambigous, and cannot be made ambigous by "extend"ing a domain or by adding a package or a domain. This problem does not (or hardly) exist in the interpreter, since the axiom library will probably not change during a mathematical experiment. > Why should the human programmer be forced to manually perform what the > interpreter is doing so well (and most likely can be even improved)?

Even with the axiom library, you will find that )sh, )di, etc. are rarely needed, since the compiler tells you quite exactly what he is missing. The combinat experience was very enlightening for me.
