Move semantics with std::initializer_list

[ahorn]

Line 1564 uses move semantics when working with std::initializer_list. But when I debug the type of, say, element[1], using clang++ 3.5 and compiling the unit tests, the compiler deduces a const reference type (see also std::initializer_list::begin). There are no meaningful semantics for moving const references so I wanted to double check with you guys.

@ahorn you are right - http://stackoverflow.com/a/8193157/266378 seems to mention the same issue.

Thanks for noting! I removed the std::move calls to remove the appearance that move semantics is applied.
