Lambda calculus - Wikipedia, the free encyclopedia
In mathematical logic and computer science, lambda calculus , also written as λ-calculus , is a formal system for function definition, function application and recursion. It was introduced by Alon...

There is actually a whole mathematical theory devoted to expressing computation entirely using lambda abstractions: the lambda calculus. Most functional programming languages (including Haskell) are based upon some extension of this idea.

3.1 Lambda Abstractions ... Nested lambda abstractions such as this may be written using the equivalent shorthand notation \x y -> x+y. In fact, the equations: inc x = x+1 add x y = x+y; are really shorthand for: inc = \x -> x+1 add = \x y -> x+y;

C++ as a functional language ... This article is to exhibit lambda abstractions in C++ in comparison with those of traditional functional languages (e.g., Scheme). The article will try to demonstrate that "applicable values" in C++ not only look similar to their functional cousins.

For what it’s worth, I think I’ve decided against relying on GCC’s trampolining to do higher-order functions and lambda abstractions in Ca. It is very clever and very efficient, but the semantics are a bit hairy for the 21st century.

The Boost Lambda Library (BLL in the sequel) is a C++ template library, which implements a form of lambda abstractions for C++. The term originates from functional programming and lambda calculus, where a lambda abstraction defines an unnamed function.
