1. Algol was the first high-level programming language to implement recursion

2. Cobol (Common Business-Oriented Language) is a high-level programming language for business applications

3. He directed the team that invented and implemented FORTRAN, the first widely used high-level programming language, and was the inventor of the Backus–Naur form (BNF), a widely used notation to define formal language syntax.

4. This is based on the assumption that the most expensive functions inside games, can be abstracted from the game logic, making it possible to use a high-level programming language, such as Python, to structure the game.
