Hope

language A functional programming language designed by

R.M. Burstall, D.B. MacQueen and D.T. Sanella at Universityof Edinburgh in 1978. It is a large language supporting

user-defined prefix, infix or distfix operators. Hope

has polymorphic typing and allows overloading of operators

which requires explicit type declarations. Hope has lazylists and was the first language to use call-by-pattern.

It has been ported to Unix, Macintosh, and IBM PC.
