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