    Type Parameters:
    
    F_ - The exact functional type to generate. Must be same as F
    
    Parameters:
    
    parameterCondition - A predicate that's true when for the given list of parameters answer should be used to produce the function' result
    
    answer - A function that produces a concrete answer or throws an exception
    
    Returns:
    
    A new instance of function arbitrary
