The solid foundation of the Lambda Calculus is integrated in a course of
the general principles of programming,
Other books introduce functional programming almost exclusively in conjunction with a specific complex programming
language like e.g. Haskell. The Lambda Calculus, if it is mentioned at all as the theoretical base for
functional programming, is always seen as a mathematical, logical system, presented in mathematical notation.
It is put on a high mathematical pedestal that is still unreachable for many people, or at least is given a
highly theoretical appearance from which many programmers conclude that they don't have a need for it.
- without restricting the presentation to a special functional programming language,
- and without treating programming as a branch of mathematics.
On the contrary, `Programmierung PUR' presents the basic operations of the Lambda Calculus,
abstraction, reference and synthesis as a simple fundamental programming language including programming examples
with its own ARS-interpreter.
