C++11 catch-up

Catching up on C++11 and C++ in general now. On one hand it doesn't feel like it makes sense, given that Perl is such a versatile tool, and I don't really do anything important, anyway. On the other hand it feels like it's worth checking out now that the new standard is out.

I've seen the C++0x label for so long that I've taken to calling C++11 C++0xB instead. I'm sure I'm not the first to think of it, but it amuses me somewhat.
