Comment (by Joaquín M López Muñoz):

 Hi,

 I see that `boost::type_traits_detail::is_likely_stateless_lambda`
 defaults out for MSVC at

 https://github.com/boostorg/type_traits/blob/5240cd67d895dd811ca708eb5faa835de73f25b8/include/boost/type_traits/detail/is_likely_lambda.hpp#L30

 but my local tests seem to show the lambda detection machinery indeed
 works for MSVC 14.0 --don't know about 12.0. Would it be possible to relax
 the aforementioned line so that MSVC >=14.0 is accepted?

 Thank you
