Since people have come up with various creative ways to break all existing code
using Boost, and I've been asked off-list "but don't you want to break things", I
want to clarify that those are completely outside the scope of my proposal. It is
exactly as outlined above, no more and no less. I do not propose "Boost 2.0",
replacing the includes with boost2/foo.hpp, replacing the library names with
libboost2_foo, bumping the version to 2.0, dropping libraries from Boost, and
anything like.
As long as a C++11 compiler is used, code that compiles and works with 1.82
should continue to compile and work with 1.83, without changes.
