The typical use-case of std::initializer_list<T> is for a pass-by-value parameter of T's constructor. However, this contravenes 220.127.116.11 [res.on.functions]/2.5 because initializer_list doesn't specifically allow incomplete types (as do for example std::unique_ptr (19.11.1 [unique.ptr]/5) and std::enable_shared_from_this (19.11.6 [util.smartptr.enab]/2)).A resolution would be to copy-paste the relevant text from such a paragraph.
