I think that is too negative to reflect reality.
Certainly compilers out there vary in what they implement of the
recent template technology, but:
* We don't need the full language and full runtime support (in
effect, G++ was notorously known not to implement the full
language nor to have a full implementation of the library nor to
have a correect implementation of the language, still it was, is
and will coontinue to be widely used);
* C++ is not reduced to templates;
* even from the templates, there is a fair core that has been stable
for a decade -- even GCC-2.7.x supports basic template constructs;
* there is a well-formed corpus of C++ well-implemented by
compilers out there. That corpus is the not the most recent
innovative features of the langage but successful projects in C++
don't always use the most recent features.
There are lots of successul C++ projects out there, and they are not
experimental ones.
CFront was written in C++, and at the time C90 compilers were not as
comon as today. Still I can't say there was so much Fear,
Uncertainty and Doubt about C++ use as an implementation language
to impmlement CFront.
Let's get rid of the Fear, Uncertainty and Doubt spread out by the
urban legend and acknowledge the fact that C++ can be used to
implement efficiently major parts of something as complex as a
compiler collection namemd GCC.
