Comment (by akrzemi1):
Visual Studio for, I think, two releases supported `dcltype` bot no
variadic templates. I really had this compiler in mind.
Whether this makes sense or not is one question, but the other question
remains. It is not strictly in the scope of this library, but could you
give me a macro that says if the is_constructible works correctly or falls
back to a negative default? Currently I had to repeat the long `#if` from
is_constructible.hpp, as I cannot rely on the 'safe' default.
