> The Delphi code generated for {{required}} fields silently ignores {{nil}} values, because {{nil}} values cannot be written. Consequently, the data stored this way cannot be read later on because of the missing members.
> {code}
> struct foo {
>    // leaving this member nil will ignore the field on write
>    // and thus make the data unreadable
>    1 : required foo  try_to_leave_me_nil   
> }
> {code}
> The expected behaviour would be to throw an exception when the code is about to write required, but unset data.
