Lightweight Languages as Software Engineering Tools Usenix Paper discussing multiparadigm programming as part of a larger topic. http://www.usenix.org/publications/library/proceedings/dsl97/full_papers/spinellis/spinellis_html/spinellis.html

UFO: United Functions and Objects UFO1.0 was implemented in UFO, and a basic compiler, generating ANSI C; was produced early in the project. This implemention evolved over time, was used to produce a wide range of applications in UFO: numeric benchmarks, programming tools, and natural language processing. Free. http://www.cs.man.ac.uk/arch/projects/ufo.html

NIAL: Nested Interactive Array Language Multi-paradigm language, merges aspects of functional array language and procedural languages. Rich set of language primitives make it easy to rapidly develop loop-free data-driven algorithms. Also Q'Nial IDE, and Nial Data Engine embeddable interpreter. http://www.nial.com/AboutNial/AboutNial.html

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. http://www.apl.demon.co.uk/aplandj/qnial.html

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. http://citeseer.nj.nec.com/386474.html
