LIFE is an experimental programming language with a powerful facility for structured type inheritance. It reconciles styles from functional programming, logic programming, and object-oriented programming. LIFE implements a constraint logic programming language with equality (unification) and entailment (matching) constraints over order-sorted feature terms. The Wild_LIFE interpreter has a comfortable user interface with incremental query extension ability. It contains an extensive set of built-in operations as well as an X Windows interface.

A semantic superset of LOGIN and LeFun. Syntax is similar to prolog.
