The Omega interpreter is a strict pure functional programming interpreter similar to the Hugs Haskell interpreter. The syntax closely resembles that of Haskell but with important differences:Omega uses strict evaluation ; Ability to introduce new kinds; Allows writing functions at the type level.

The Omega interpreter1 (sometimes written as Ωmega) is a strict pure functional programming interpreter similar to the Hugs Haskell interpreter. The syntax closely resembles that of Haskell but with important differences:

Other differences are documented in the Omega user guide.1

Omega was developed by Professor Tim Sheard of Portland State University's Computer Science Department as a language with an infinite hierarchy of computational levels, e.g., value, type, kind, sort. The underlying concept is that data, and functions manipulating data, can be introduced at any level.2
