If so, we can temporarily modify the trait to exclude the last

as the last member.

Note that `std.traits.isCopyable!S` cannot be used, because it 
will return true when `S` has uncopyable members regardless of 
whether S.tupleof have any extra void* element or not (because of 
S's disabled postblit).
