Hmm, yeeeeessss.......

Me, I dislike anything that says "Lisp" in it. :-S

I gave up when the language libraries were so obviously stupid...

That's a miracle. It's a pretty rare language...

Didn't try it personally, no. But that's what the language spec says. 
(IIRC it's an ISO standard now or something?)

Note that Eiffel Studio isn't the only implementation. There's Smart 
Eiffel (AKA Small Eiffel) that reguarly does quite well in the language 
shootout benchmarks... But either way, the libraries are very poor.

[E.g., Eiffel provides strong generics support with a whole heap of 
infrastructure to support writing really generic code. So they designed 
one class for character I/O, and a completely unrelated one for binary 
I/O. GAH! >_< Why?!]
