  13 __inherit If T is a (possibly cv-qualified) type with a non-throwing destructor
  14 then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
  15 must be a complete type.
  16
  17 __compat Either requires C++11 `noexcept` and `decltype` or else some (unspecified) help from the compiler.
  18 You may test to see if the necessary support is available
  19 by checking to see if `!defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT)` is true.

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