Comment:

 I have implemented a solution based primarily on stevens suggestion since
 using BOOST_MPL_HAS_XX_TRAIT_DEF improves compiler support.

 I have chosen to implement this using enable_if to select a base class
 since this works better on many compilers (due to the base class being
 dependent on the template parameters) than the snippet posted above.
