 ISWIM

ISWIM (short for "I'm Still What I Mapped") is a programming language that was developed in the early 1970s as an experimental language for teaching and research in the field of computer science, particularly in the area of programming language design and implementation. ISWIM is notable for its influence on subsequent programming languages and its contributions to the study of functional programming. The language was introduced by Peter G. Neumark and later developed with contributions from others including Robin Milner.
