It's probably fashionable to throw rotten tomatoes at me now, but I do quite like that little language. Simple to get to grips with, but with enough capacity to be brainbendingly wierd if you want it to be, and enough syntactic sugar to be oh awesomely sweet in places.
The only problem it ever had is it's not the fastest interpreted language in the world. Faster than BASIC but not by all that much. 1.9.x improved that. Let's see what 2.x does!
