22 checked deleters are used to make sure that the type being deleted is really
23 a complete type.: otherwise sizeof() would result in a compile-time error
24
25 do { ... } while ( 0 ) construct is used to have an anonymous scope
26 (otherwise we could have name clashes between different "complete"s) but
27 still force a semicolon after the macro
