C++0x standard is in "real soon now" mode for quite some time. I'm definitely excited by the possibilities, but somewhat unhappy over the current state of compilers, see e.g., http://wiki.apache.org/stdcxx/C++0xCompilerSupport and http://gcc.gnu.org/projects/cxx0x.html

In such as scenario, writing code that runs with different OS-compiler combinations while leveraging the cool features such as concepts, lambda expressions and closures, variadic templates and unicode is going to be difficult in the short term. Of course, if a project sticks to a single compiler, then it won't be much of an issue.

Nowhere near the power offered by LISP, but huge leap of convenience while writing in C++

How's LISP run time compare? Most of the time I'm concerned with speed for applications (and near zero response time).

There was a formatting problem with my previous comment. The statement "Nowhere near the power offered by LISP, but huge leap of convenience while writing in C++" was a footnote for "lambda expressions and closures." The asterisk got eaten when I posted the comment, :(

Juicy description pdf. Looking forward to language multithreading, and concepts/variadic templates (no more wrong template assumptions).
