O'Haskell

The O'Haskell homepage

O'Haskell is

the purely functional language Haskell, conservatively extended with
- subtyping
- monadic objects
an object-oriented imperative language, enhanced with
- parameteric polymorphism
- automatic type inference
a concurrent language, with
- a reactive communication model
- asynchronous and synchronous message-passing

all at the same time. The O in O'Haskell should be interpreted as standing for both Objects and what remains of IO when the Evil I is removed.

O'Haskell is currently being developed at Oregon Graduate Institute and Chalmers University of Technology by Johan Nordlander, Magnus Carlsson, and Björn von Sydow.
