Actually, lambda expressions were used to debunk the myth of the
expensive procedure call, which helped the adoption of the
structured programming languages that we all use today. The elegance
of lambda expressions isn't just appealing from an aesthetic
viewpoint, but their mathematical properties make it straightforward
to implement program transformations that can make programs better
suited for our computers.
