Miranda
(From the Latin for "admirable", also the heroine
of Shakespeare's Tempest) A {lazy} {purely functional}
programming language and interpreter designed by {David
Turner} at the {University of Kent} in the early 1980s. It is
sold by his company, {Research Software} Limited. It combines
the main features of {KRC} and {SASL} with {strong typing}
similar to that of {ML}. Implemented for {Unix} by Allan
Grimeley, Computer Lab., UKC. There is also a version that
runs on {Intel 80386} and above {IBM PCs} under {Linux}.
It features terse {syntax} using the {offside rule} for
indentation. The {type} of an expression is inferred from the
{source} by the {compiler} but explicit type declarations are
also allowed. Nested {pattern-matching}, {list
comprehensions}, {modules}. {Operator sections} rather than
{lambda abstractions}. User types are algebraic, and in early
versions could be constrained by {laws}. Implemented by {SKI
combinator} reduction. The {KAOS} operating system is written
entirely in Miranda.

Translators from Miranda to {Haskell} (mira2hs) and to {LML}
(mira2lml) are available, {(ftp://www.foldoc.org/pub/)}.
Non-commercial near-equivalents of Miranda include {Miracula}
and {Orwell}.
