Lightweight Languages as Software Engineering Tools - Usenix Paper discussing multiparadigm programming as part of a larger topic.

404 Lucid - Functional dataflow language, invented by Bill Wadge, Ed Ashcroft. Variables and expressions denote streams-sequences of data items. Input and output are streams, so a program is a Unix-style filter. Was basis for French real-time/reactive languages Lustre, Signal.

500 Multiparadigm Parallel Programming Environments - Text and diagrams on two main parallel programming paradigms (data parallel, explicit message passing), and sequential multiparadigm programming with corresponding parallel versions.

Multiparadigm Programming Group - At Leibniz Laboratory, Grenoble, France; research topics, news, publications, members. In English and Français.

Multiparadigm Programming Language - Brief description, language list sorted by count and supported paradigms. [Wikipedia]

Needle - Pure object-oriented, functional language, statically typed, garbage collected; mixes ideas from Dylan, Lisp, Scheme; ML; Cecil, Smalltalk; description, slide show, downloads, links. [Open Source, MIT]

Nial Systems Ltd. - NIAL, Nested Interactive Array Language, mixes aspects of functional array and procedural languages. Rich primitives set makes it easy, fast to code loop-free data-driven algorithms. Also Q'Nial IDE, and Nial Data Engine embeddable interpreter. [Open Source, Artistic Licence]

500 Nial: A Quick Look at Nial - The basis of Nial is the array theory of Trenchard More, a body of work which underpins APL2 nested arrays. It has a low profile, but serves the same niche as APL-J.

Object Oriented and Procedural Lisp - Brief, well written description of Lisp as a Framework Language, and benefits thereof.
Meta Description: [ Object-oriented, functional, and procedural Lisp ]

Meta Description: [ Software Composition Group, IAM, University of Berne ]

ResearchIndex: From Competition to Amalgamation of Different Programming Paradigms - Describes basic elements (data, actions, tunings, voids, mixtures, ...) and principles of programming (stratification, implicit knowledge, limited freedom, ...), directed to amalgamating different programming paradigms (imperative, object-oriented, functional, constraint, ...) in a unified process of generating computer system models.
Meta Description: [ This paper describes the basic elements data, actions, tunings, voids, mixtures, and principles of programming stratification, implicit knowledge, limited freedom, directed to amalgamating of different programming paradigms imperative, object oriented, functional, constraint, in a unified process... ]
