The front end for the comeau compiler is from Edison Design Group, and that's the one that is used by many other compilers. And the EDG compiler is regarded as being the most conformant. Besides MS and the FSF (visual c++ and gcc), both Sun and IBM have c++ compiler toolchains not based on EDG. If they were, my life would be much simpler. The late additions of the STL, and some concommitant changes to how templates worked, really caused a lot of the difficulties in implementation. That, and the installed base problem. Having version N of a language change the meaning of programs targetting version N-1 tends to upset users. The STL, however, brings a very applicative programming model into an otherwise imperative language. And, it turns out that the template language is a turing complete pure functional language, making possible some very interesting type based metaprogramming. Of course, since it wasn't really designed as such, it has to be heavily sugared to be useful.

Algol-68, Pl/1, Ada and now C++ becomes such large languages that no one can master them in full details -- Best regards, Bulat mailto:[EMAIL PROTECTED] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
