[section:has_nothrow_destruct has_nothrow_destructor]

   template <class T>
   struct has_nothrow_destructor : public __tof {};
  
__inherit If T is a (possibly cv-qualified) type with a non-throwing destructor
then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
must be a complete type.

__compat Either requires C++11 `noexcept` and `decltype` or else some (unspecified) help from the compiler.
You may test to see if the necessary support is available 
by checking to see if `!defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT)` is true.

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

[note
Note that destructors are assumed to be non-throwing unless they are explicitly marked otherwise with a `throw(something)` specification.
This is in line with the C++11 standard.
