The only reason this failed to compile on VS 2013 was because the compiler uses different initializer_list constructor argument types than our dummy implementation. The standard does not specify the non-default constructor argument types for initializer_list. Use a template to match any two-arg constructor a compiler might select (e.g. begin/end or begin/len). Use #error to preserve the error on VS 2013.
