            New With {.Name = "Michelle", .Age = 24}
        }

        Dim nameBeginsWithM = Function(name) name.ToUpper.StartsWith("M")
        Dim ageIsEven = Function(age) age Mod 2 = 0

        Dim peopleOver20 = people.Where(Function(person) person.Age > 20)
        Dim peopleWithNamesThatBeginWithM = people.Where(Function(person) nameBeginsWithM(person.Name))
        Dim peopleWithEvenAges = people.Where(Function(person) ageIsEven(person.Age))
