:relfileprefix: ../../../
:mrdocs:

Return a movable reference to the specified `lvalue`. This function is selected by overload resolution if the move constructor for `t_TYPE` is nothrow‐move‐constructible. Constructing a `t_TYPE` object from the result will result in the (safe) move constructor being invoked. Note that that the `bsl::is_nothrow_move_constructible` trait can be customized in C++03 mode to indicate that a type is nothrow‐move‐constructible.
