language (From the Latin for "admirable", also the heroine of Shakespeare's "Tempest") A 
lazy purely functional programming language and 
interpreter designed by 
David Turner of the University of Kent in the early 1980s and implemented as a product of his company, Research Software Limited. Miranda combines the main features of 
KRC and 
SASL with 
strong typing similar to that of 
ML. 
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. It has nested pattern-matching, list comprehensions and 
modules. It uses operator sections rather than lambda abstractions. User types are algebraic, and in early versions could be constrained by 
laws. 
It is implemented using SKI combinator 
reduction. Originally implemented for 
Unix, there are versions for most UNIX-like platforms including Intel PC under 
Linux. The 
KAOS operating system is written entirely in Miranda. 
Translators from Miranda to 
Haskell (mira2hs) and to 
LML (mira2lml) are available at (https://foldoc.org/pub/misc/). Non-commercial near-equivalents of Miranda include 
Miracula and 
Orwell.
