This isn't really a problem as it can be easily fixed. It's just
that the original writer of Scoped made the mistake of allowing
implicit conversion of a Scoped!C to a C, which when you think
about it doesn't make any sense and is actually quite dangerous
(as my post that you cited shows). All that has to be done to fix
that is to disallow implicit conversion to the wrapped type while
retaining the interface, which we can do today with a myriad of
different methods (mixins, opDispatch, std.typecons.Proxy, etc.).
It's just that nobody has done it.
