Basically this means that different people and tasks need different
languages. The intention of "one size is to fit all / to cover all needs"
leads to a very complex solution.

Given that there are needs and people satisfied with C++ without
templates and exceptions, it would be nice to keep that "pre-"standard
and implementation alive.

I have one extremely important application, the Coda file system,
which belongs to this class. The complexity of modern C++ compilers
is several orders of magnitude bigger than of the application itself.
This is bad, for several reasons (begin with security...).

Another very useful tool, FLTK, looks to be compatible with cfront
and also is much less complex than the modern development tools.

So it is not wrong per se to have a complex language, but the fault is to
"pretend" that the next C++ version becomes better for all purposes and
is expected to be the only available/used one.

Strictly speaking each version is a definition of a new language,
but an appearance of a new language does not render the other ones
obsolete. The versions are treated like they do obsolete the previous
ones, which is actually not true.

Sounds just right.
