The following is understood as a contribution toward a field of com-puter science education : a reflection of 5 months of learning the functionalprogramming language Haskell; out of which has emerged for us that pro-gramming languages are ‘just other programs’. This lesson, so important,is never felt more than in a functional language like Haskell, we defend. Ithas for principal benefit to bring down the barriers between creators andusers of programming languages, i.e. “programmers”, both are the same;a psychological-sociological fact not without revolutionary characteristics.
