You and your team already fixed all my showstoppers (template 
aliasing, packed parameter parsing), including in that recent VS2013 
update. I am very grateful. For the list's information, Stephan and 
his wider team turned around those fixes in two weeks, very 
impressive. You've made the APIBind technique fully functional on 
MSVC which I hope will form the foundation of a C++11 only 100% 
modular Boost 2.0 (c.f. my C++ Now presentation next week + shortly 
to be released Handbook of C++ 11/14 Library Best Practices).

The only remaining big flaws for me are the lack of two phase lookup, 
and that C++ 11 constexpr is pretty useless (which isn't Microsoft's 
fault, but C++ 14 constexpr is enough not a headache to use to bother 
with using).

BTW are you willing to document how your STL invokes the magic 
Expression SFINAE support in MSVC? I understand you don't want people 
using internal magic compiler hooks, but I can also see that some 
Boost authors (I'm thinking Louis and his Boost.Hana) would be very 
interested.
