> One of the effects of ISLISP was to legitimize various dialects of Lisp that did not want or need to be Common Lisp. By being ISLISP compliant, they have some degree of interchange capability with one another.
Which dialects are those? As far as I can tell, the main non-CL influences recognized by the ISLISP spec (EuLisp, Le-Lisp, and Scheme) all pretty much ignored ISLISP entirely (except for perhaps EuLisp, which may or may not have been canceled to make way for ISLISP... I'm still investigating the history of that one... in any case, EuLisp was very different from ISLISP).
At this point in time, the only ISLISP implementation I can seem to find is OpenLisp from Eligis, who was previously a Le-Lisp vendor. Here and there, I've found references to about three other implementations, but they all seem to have been wiped off the Web and no longer exist.
On a tangent, EuLisp was absolutely beautiful, and it's a real shame that it was never finished. It also had some "new" things to offer the world of standardized Lisps, whereas ISLISP really doesn't offer anything that couldn't already be found in Common Lisp.
Dialects of Lisp that don't want to be Common Lisp probably also don't to be ISLISP even less.
If I'm a hacker with ideas about implementing Lisp, I'm not about to whip out ISLISP and conform to it as a starting point. I'm going to invent everything from scratch and kind of just borrow things here and there from other dialects.
Therefore, its existence has no bearing on legitimizing what I'm doing. In fact, the existence of yet one more standard that I'm not conforming to is only undermining my legitimacy. ("There are seventeen standards; why are you inventing something new? Must be not-invented-here syndrome!")
