Is this a known issue? (It should repro for other platforms, although I haven't checked.)
I dont know how much of this is a largely known issue, but this a problem on C++11 compilers(such as gcc or clang) that I have seen when I was using Boost.Assign on both C++11 compilers and MSVC. I always had to use workarounds to get it work on C++11(which Boost.Assign was already a workaround for MSVC).
Should this conversion operator be constrained so it can't be instantiated for initializer_list?
Yes, ideally, the conversion operator should use default template parameters to exclude initializer lists on compilers that support this. I dont know if VS 2013 supports default template parameters for functions, or not.
