    template<typename F, typename C>
      scope_fail< typename std::decay< F >::type, typename std::decay< C >::type >
      make_scope_fail(F && func, C && cond, bool active = true);

## Description

Effects: Constructs a scope guard as if by calling `scope_fail< std::decay_t< F >, std::decay_t< C > >( std::forward< F >(func), std::forward< C >(cond), active)`.

Parameters: |

`cond` | The callable failure condition function object.
