/* Defect report 1467 denounces that for aggregate types an intended {}-style
 * copy construction will be mistaken for aggregate initialization:
 *   http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1467
 *
 * A solution is to define a default constructor for the offending class so
 * that it is no longer an aggregate.
