Comment:

 I do not have access to the latest msvc2015 right now. Could you apply
 your patch and run all the tests from boost_root/libs/variant/test. Just
 go to that folder and run ..\..\..\b2 from it.

 If everything is OK, than it's a good sign not to increment 1900 next time
 :) Unfortunately it's impossible to enable variadics for _MSC_VER == 1900,
 because there's no known to me way to distinguish vs2015 update 2 from
 older versions (update 1 and before) and Boost must be able to run on any
 compiler.

 > oh variant based on mpl - why?
 Variant was created long before variadic templates appeared. Since then
 variant uses MPL.

 > when limitations will be removed?
 When Boost.MPL will be transfered to variadic templates. That's a big task
 and nobody has time or will to do it right now. However pull requests are
 always welcomed ;)
