HOPE is a historical programming language created in 1978. Hope is a small functional programming language developed in the 1970s at Edinburgh University. It predates Miranda and Haskell and is contemporaneous with ML (also developed at Edinburgh). Hope was derived from NPL, a simple functional language developed by Rod Burstall and John Darlington in their work on program transformation. Read more on Wikipedia...
