CLU (programming Language)

CLU is a programming language created at MIT by Barbara Liskov and her students between 1974 and 1975. It was notable for its use of constructors for abstract data types that included the code that operated on them, a key step in the direction of object-oriented programming (OOP). However many of the other features of OOP are (intentionally) missing, notably inheritance, and the language is also hindered by a sometimes frustrating if elegant syntax.
