AnyFalse()

bool AnyFalse<TMetadata>(this IEnumerable<BooleanResultBase<TMetadata>> results)

The AnyFalse() extension method is used to determine whether any of the boolean results are not satisfied.

IEnumerable<BooleanResult<int, string>> results = 
    [
        new IsEvenProposition().Evaluate(1),
        new IsGreaterThanProposition(5).Evaluate(6)
    ];

results.AnyFalse();  // true
