... no, it's because the private Scoped_store is passed out via 
the Scoped_payload property.

Anyway, the actual scoped() method itself is templated, so 
whether it can be @nogc or not obviously depends on its arguments 
and has to be inferred.  The trouble is with the destructor 
~this() which is in no way dependent on template parameters, but 
in calling the destructor of the scoped payload, depends on the 
payload's own destructor for whether it can be @nogc or not.
