I think you have a good chance of getting it working on VS2017,
though with some effort by you to do the port. Not bastardising it,
but rather reformulating your code to work around lack of two phase
I hope you're not using lambdas in template template parameters.
Chandler tells me MSVC can't mangle some of those, and has to stop
dead same as winclang has to.

I have found VS2015 quite remarkably better than anything before. In
developing my lightweight monad recently which involves plenty of
hefty C++ 11 and 14 metaprogramming, I mainly used clang 3.6 on
Linux, and then pushed changes to my Jenkins CI without any further
Out of 100 builds, about four failed with GCC 5.1 due to GCC having
incomplete/buggy constexpr support.
Out of 100 builds, less than ten failed on VS2015 due to me using a
construct it didn't like. Of course, I was deliberately avoiding
Expression SFINAE etc, but the point is that VS2015 has enormously
closed the gap with clang and GCC. Over 90% of the time in my case
these last few weeks VS2015 will compile any C++ 11 or C++ 14 I wrote
and tested only using clang on Linux. That's quite something compared
to where we were only a year ago.
