Icon was developed by Ralph Griswold and others in the late 1970s as a successor to Snobol. Unlike Snobol, it resembles the Algol family of languages (e.g. C or Pascal). It is unusual in that it uses backtracking as a major control flow construct in the form of "generators" which can be reactivated by backtracking to generate successive values of a set.
