Comment (by johnmaddock):

 Hold on a second - type T in your example is not IMO trivially copyable
 (because it's not copyable at all).  I realise some interpretations of the
 std will result in std::has_trivial_copy returning true for this type, but
 that seems to be bonkers to me.  It has always been (deliberate)
 Boost.TypeTraits behaviour for such types to be non-trivial.

 What am I missing?
