Then the real issue maybe is the following: what are we going to do vs C++0x
features? Shall we set-up the compiler switch for it (-std=c++0x?) and start
adding things? Or people believe it's too early? Maybe a good compromise would
be wait for inclusion in the draft, to wit before C++0x (but later than now for
variadic templates, for example)?

It's a chicken-and-egg problem. Nobody on the committee wants to standardize
anything that isn't "existing practice," but we only want to accept patches for
features that have been written into the current working draft. How will C++0x
ever move forward?

GCC is uniquely situated to lead the way to C++0x. Our support for C++03 is
excellent, and the code is open and (relatively) accessible to experimenters.
There are patches "out there" for rvalue references, decltype, variadic
templates, and concepts, among other things. If the patch is ready, and we
think the feature is worth pursuing, we should accept the patch. Our acceptance
allows greater experimentation with and understanding of new ideas within the
C++ community and how they interact, and will improve the C++0x language as a
whole. Of course, it also means that GCC will have one of the most mature
implementations of the upcoming C++0x features once C++0x is finally written in
stone.

For the record, personally and for what is worth my personal opinion in the
compiler area, I have nothing against adding to the compiler -std=c++0x and
start adding things, in general. I'm also finding a little "adventurous" adding
complex features which are not reasonably likely (not my call assessing that)
to be accepted for the next standard. If someone is interested in knowing my
opinion, I would certainly be in favor of rvalue references and concepts, a tad
less for variadic templates.

For the record, I'm strongly in favor of variadic templates. Key parts of TR1
(tuple, functional) necessitate some kind of compiler support in order to have
full implementations: the current limits on tuple size are an embarrasment. The
current implementation strategies for these library elements are highly complex
and far too pre-processor slap-happy for my comfort or taste.

As these parts of TR1 are already (as of Berlin) part of C++0X, I think it
behooves the C++ community to "get real" about robust solutions.

I think starting -std=c++0x is a great idea.

I second that.  In addition to that I would welcome a warning for current C++
if I use keywords that are reserved in C++0x.

We should have -std=c++2003 and -std=c++0x.  However, care must be
exercise about what is included in both options.

So what will "-ansi -pedantic-errors" use?  c++98, 2003, or 0x?

I think we should simply learn from the C front-end, thus C89 vs C99, etc.

[Bug c++/20599] variadic template support

[dgregor at gcc dot gnu dot org]

------- Comment #16 from dgregor at gcc dot gnu dot org  2007-03-28 15:30 -------
This functionality is part of the experimental C++0x mode, and is under control
of the -std=gnu++0x flag in the mainline (4.3.0) compiler.
