Comment (by johnmaddock):

 Thanks that's really neat!

 Hopefully Frederic Bron will take this up as he's much more familiar with
 the internals of these traits than I am.

 Note that the issue effects not just the unary operators, but all the
 binary operators such as has_plus etc suffer the same issue.

 We also need to figure out what config macros will determine when the
 above approach can be used - BOOST_NO_CXX11_FUNCTION_TEMPLATE_DEFAULT_ARGS
 and BOOST_NO_CXX11_DECLTYPE certainly, possibly BOOST_NO_SFINAE_EXPR as
 well.
