I find scheme error messages much friendly the common lisp (which some would say bucks the trend a bit, but they are both lisp I guess).
Also, dynamic typing, and type inference can result in massive bum-steer errors. Its boring staticaly typed languages that tend to be more friendly for error messages. eg most java compilers will tell you, to annoying accuracy what you should have said, where you should have put a ; etc... (which makes you think, why doesn't it just do it !). Some dyn langs to better then others, I think python isn't too bad, but I find ruby really noisy and wierd when I stuff up.
This is simply not true, especially the last part. This comes from experience, on both ends.

Computer languages "feedback" (error messages, etc.) is poor. It's interesting: you can find hundreds of blog posts about syntax, garbage collections, string libraries or whatever but nobody seems to care about error/warning messages. It's a thing that hasn't evolved since a long time.
