Modula-3

L. Cardelli et al, DEC and Olivetti, 1988. A descendant of Modula-2+ and Cedar, designed for safety and simplicity. Objects, generics, threads, exceptions and garbage collection. Modules are explicitly safe or unsafe. As in Mesa, any set of variables can be monitored. No multiple inheritance, no operator overloading. Uses structural equivalence. "Modula-3 Report", Luca Cardelli et al, TR 52, DEC SRC, and Olivetti Research Center, Aug 1988 (revised Oct 1989). The changes are described in "System Programming with Modula-3", Greg Nelson ed, P-H 1991, ISBN 0-13-590464-1. "Modula-3", Sam Harbison, P-H 1992. Version: SRC Modula-3 V1.5.

Modula-2

<language> A high-level programming language designed by Niklaus Wirth at ETH in 1978. It is a derivative of Pascal with well-defined interfaces between modules, and facilities for parallel computation. Modula-2 was developed as the system language for the Lilith workstation. The central concept is the module which may be used to encapsulate a set of related subprograms and data structures, and restrict their visibility from other portions of the program. Each module has a definition part giving the interface, and an implementation part. The language provides limited single-processor concurrency (monitors, coroutines and explicit transfer of control) and hardware access (absolute addresses and interrupts). It uses name equivalence. {Modula-2/m2.tar.Z">DEC FTP archive (ftp://gatekeeper.dec.com/.1/DEC/Modula-2/m2.tar.Z)}. ["Programming in Modula-2", N. Wirth, Springer 1985]. (1995-10-25)

Modula-3

Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+. While it has been influential in research circles (influencing the designs of languages such as Java, C#, Python and Nim) it has not been adopted widely in industry. It was designed by Luca Cardelli, James Donahue, Lucille Glassman, Mick Jordan (before at the Olivetti Software Technology Laboratory), Bill Kalsow and Greg Nelson at the Digital Equipment Corporation (DEC) Systems Research Center (SRC) and the Olivetti Research Center (ORC) in the late 1980s.

Modula-3's main features are simplicity and safety while preserving the power of a systems-programming language. Modula-3 aimed to continue the Pascal tradition of type safety, while introducing new constructs for practical real-world programming. In particular Modula-3 added support for generic programming (similar to templates), multithreading, exception handling, garbage collection, object-oriented programming, partial revelation, and explicit marking of unsafe code. The design goal of Modula-3 was a language that implements the most important features of modern imperative programming languages in quite basic forms. Thus allegedly dangerous and complicating features such as multiple inheritance and operator overloading were omitted.
