Synchronized-and-the-like interface types are limited, so the built-in-
place is indeed really built-in-place (no kind of conversion allowed
at any stage). The initializer function have to return a class wide
and return it using an extended return statement which is required to
return the same exact type/subtype as the one function returns.
This way of doing thing is not compatible with the implementation-
hiding requirement, as it would require the implementation type to be
exposed in the public part, so that I could define a public function
returning this exact type.
