An OO extension for Jacl, by Neil Madden. This is a work in progress, and I haven't released anything yet. It should allow some interaction with Java objects. Initially this will be in the form of being able to implement Java interfaces in Hyde, with the potential for subclassing java classes later on.
NEM 24 May 2004: This project never really got off the ground. I'm still toying with the idea, but I no longer use Jacl, so it's unlikely to happen soon (although, I will probably have to work with Java again in the future, in which case I might take up the project again). Also, there is another project called Hyde for Jacl, which is an equivalent to critcl, if I remember correctly.
