Uniform initialization fails to copy when object has no data members

by

This is a known bug and will hopefully be fixed in C++17 (not for C++14, see http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1467). Your struct is an aggregate, so to initialize it with {someElement} there needs to be at least one data member, as you have discovered. Try providing an operator int(); and you will see it compiles.
