I really like a lot of the new features coming out in C++ and many of them can be enabled without additional core language features. This library is just a collection of (mostly other people's) implementations of the features I want.
I take it I'll get very few questions. Thus, a true FAQ would be very short.
In many cases, Boost has similar implementations. However, since a lot of those implementations were earlier incarnations of what eventually became C++ TSes, their interfaces differ slightly from what eventually becomes ISO. They (rightly) don't want to change the interfaces their own users already use.
