i looked at lush several times, but somehow never got into it. some of the things that put me off: the fact that sdl and opengl were not supported under windows (my primary interest was in developing desktop applications and small games), the dynamic scoping (i'm a scheme fan; not having lexical scoping throughout just feels offputting) and the (real or perceived) lack of a strong community. it did look like a great language, though, and i was rooting for it despite never finding a good use for it myself.
