As Sam Harbison writes in his book Modula-3,

Welcome to the world of Modula-3!

Modula-3 is a new member of the Pascal family of languages. Designed in the late 1980s at Digital Equipment Corporation and Olivetti, Modula-3 corrects many of the deficiencies of Pascal and Modula-2 for practical software engineering. In particular, Modula-3 keeps the simplicity of type safety of the earlier languages, while providing new facilities for exception handling, concurrency, object-oriented programming, and automatic garbage collection. Modula-3 is both a practical implementation language for large software projects and an excellent teaching language.
