C++0x fluidity

[Martin Eisenberg]

Suppose I started doing my stuff in the dialect that current GCC
calls C++0x. Am I likely to have big rewrites coming my way when the
standard is finalized?

I would say it depends on the features you think about and their
maturity. For example, the details of the rvalue reference semantics
are *probably* going to change.

Also, last time I checked (at least my g++ version at home) is buggy
w.r.t. rvalue references. See

Thanks. What lures me most right now are concepts and variadic
templates, what about those?

Variadic templates looks reasonably stable, so there is just the
portability question (gcc 4.3+, only?).

Concepts are only available in a VERY experimental ConceptGCC, which
doesn't implement the latest proposal and tends to fall over if pushed
anywhere near its limits. Useful for playing around with, but not much
more.
