First, Clang 3.5 is now fully supported. Second, you imply that any
library which uses variable templates, extended constexpr or other
C++14 features that are not well supported yet is not suited for
real use. I humbly disagree.
On the contrary, I think it is a good occasion to push compiler implementers
a bit by making more cutting-edge libraries available to the large public.
Then, there will be a bigger incentive to support C++14 properly, but most
importantly there will be more bug reports comming in, which triggers
I hope the rest of this community is not feeling the same towards
cutting edge libraries. I would suspect that some of the most
groundbreaking libraries that are now well accepted and supported
by compilers were in Hana's position when they started.
