[section:is_default_constructible is_default_constructible]

   template <class T>
   struct is_default_constructible : public __tof {};
    
__inherit If `T` can be default-constructed
then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
must be a complete type.

__compat This trait requires the C++11 feature `decltype` support for full support.
While there is some fallback code for cases where this is not the case, the trait should really be considered broken in that case.

__header ` #include <boost/type_traits/is_copy_constructible.hpp>` or ` #include <boost/type_traits.hpp>`
