I tried out Smalltalk for a day and I was completely amazed by the some of the features that still haven't made it into other languages. One of the features that I remember in particular was the ability to search for functions by examples. I don't remember the exact syntax for it, but you could search by something like:

    "hi" => "HI"

and Smalltalk would tell you "toUpperCase". Immediately after seeing this, I wanted the languages that I use everyday to be able to do it.
