Completely agreed. But this does also highlight the importance of proper 
workarounds. The current thing is a great example:
A workaround for a MSVC bug was included in the RC. However the code for 
that was invalid C++ and guarded by a `_MSVC >= xxxx` version macro. 
Hence a bug in MSVC was fixed by using another bug in MSVC with the 
assumption the latter will not be fixed (soon).

My point is: Even those workarounds should be expected to work in the 
future by using proper C++ (as far as possible) which now is the case 
(thanks for the ones working on that). I see that once a project 
switched to a Boost version they stay there for quite a while and for 
those this will be a huge problem (Please don't argue that they could 
simply update boost. Sometimes newer Boost have breaking changes/new 
bugs in other libraries that prevent this [Boost.Serialization e.g.])
