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
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.
