Abstract: We address a problem connected to the unfolding semantics of functional programming languages: give a useful characterization of those infinite lambda-terms that are lambda_{letrec}-expressible in the sense that they arise as infinite unfoldings of terms in lambda_{letrec}, the lambda-calculus with letrec. You can describe typeless lambda calculus with just a few formulas in operational semantics. We provide two characterizations, using concepts we introduce for infinite lambda-terms: regularity, strong regularity, and binding-capturing chains. I won't go into all the reasons why it's better to write computational systems in a functional paradigm since that is covered in depth in my forthcoming book “Computational Finance and the Lambda Calculus”. While the only thing (with the exceptions mentioned below) you can really manipulate with A++ The addition that A++ makes to lambda calculus is the ability to explicitly assign names to objects (functions or values), something which lambda calculus only supports through binding via function calls. We then look at the basic building blocks and the philosophy of the language, discussing concepts such as the lambda calculus, closures, currying, immutability, lazy evaluation, memoization, and the role of data types in functional languages. Lambda calculus was designed to investigate problems related to calculation. However types can have diminishing returns as more types are introduced. Update: Apologies to anyone who's sensibilities were offended by the claim that A++ is a "purely functional" language. Programming is that it's easy to define and implement.

But before I get to it, I'd like to talk a little about the connection between generic programming and functional programming, give a short intro to functional programming; and then show some examples in C++ and D that involve pattern matching and type lists. The STL function bind1st, bind2nd and binary_compose can be used for currying. Functional programming, therefore, primarily deals with calculation, and, surprisingly, uses functions to do so. It makes many things considerably easier on programmers. An Introduction to Functional Programming Through Lambda Calculus. Posted by Liang Yi at 12:24 AM.
