      In the following tables, T
      and U are the types that the
      operation applies to, R is
      the result type. T always defaults
      to _self to match the default
      behavior of any. These concepts assume normal semantics. Thus, comparison operators
      always return bool, and references will be added to the arguments and results
      as appropriate.
    
      Except as otherwise noted, primitive concepts defined by the library can be
      specialized to provide concept maps. copy_constructible,
      and the iterator concepts cannot be specialized because they are composites.
      constructible,
      destructible,
      typeid_, and same_type cannot be specialized
      because they require special handling in the library.
