Hi all, I'm pleased to announce the availability of O'Hugs 0.4 -- the first public release of the O'Haskell User's Gofer System! O'Haskell is an object-oriented extension to Haskell, offering both polymorphic subtyping [1] and monadic reactive objects [2] in addition to the beloved Haskell core. O'Hugs 0.4 is based on the sources for Hugs 1.3b, so Haskell 98 compliance is currently lacking, but this should hopefully not hinder those interested in object-oriented functional programming from exploring the language. More information, programming examples, as well as the full distribution (which also includes Yet Another Typed Interface to Tk) can be found at http://www.cs.chalmers.se/~nordland/ohaskell/ Feedback, comments, suggestions and bug reports are of course most welcome! -- Johan =============================================================== [1] Johan Nordlander.
