Firstly, this seems like something there'd already be a topic about,
but i didn't see it. Also, i'm not sure if this is the right place to
ask, but...

What C++0x features are most relevant to you? I'm curious about what
others consider good features to know, but mostly which they actually
want to use. I am personally invested in rvalue references,
std::thread, and std::initializer_list.

Though, i don't think initializer_lists are crucial to know, they were
interesting to add in my programs. That is the type of thing i'm
really curious about; the parts of C++0x that have a neat use, whether
or not it's the best part.

I think std::thread is an interesting issue: The question is if teams
that already use threads will be tempted to use what API worked in the
past and what incentives we'll have to change our threading code to
std::thread (or adapt it for a new subproject if other project already
use a proven API).

After a quick view of http://en.wikipedia.org/wiki/C%2B%2B0x I'd say
that auto, <regex> and default'ed / delete'ed special member functions
is what I'm looking forward to as most useful.
* auto should help write clearer code
* It's a long time sionce I've written anything where a regexp didn't
come in hand at one point or the other - and having it in the stdlib
saves me from having to pull in boost for just that.
* =default / =delete really looks great in that it should allow for
writing classes with more correct interfaces from the start.

br,
Martin

Rvalue references, decltype, variadic templates and SFINAE extended to
expressions (a small thing, but extremely powerful).
Multithreading support is nice as well, but it was already there even
if non-standard.

Re-using (bad pun intended) the parent constructor is a nice little
thing as well. Lambda are disappointing since they're only
monomorphic, but I may still end up using them.
The new for-loop is definitely nice sugar, even if auto makes it less
useful.
User-defined literals seem to have potential to be interesting, but I
haven't considered anything with these yet.

I'm not sure that's the right question to ask. Viewed in isolation, C+
+0x does have quite a number of neat features. But the most positive
impact may well be synergism between features, both new and old, major
and minor.

I wasn't the first to notice that. Lawrence Crowl described some of
the very positive feature interactions in a Google tech talk quite a
while ago.

So you might want to ask about features that play well together.

lamda expressions. IMHO, binders are annoying and requiring a
separate function/functor for for STL algorithms can hurt code
comprehension.
