Lambda the Ultimate

According to the website, Aldor will be open source soon. See also: an old call to open the source, with a link to an online petition, and a recent and as-yet-unanswered query on the Aldor mailing list about the opening of the source.

In a related note, there was a patch to Aldor that I found a few years ago called "Aldor--", but search engines are useless in helping me find this. Does anyone remember this?
