A bit off topic, but Icon is such a language. http://www.cs.arizona.edu/icon/
In Icon, control structures operate based on the success or failure of _expression_ evaluation. A boolean is just a value, null is just a value given to uninitialised variables. There is no "truthiness" at all. Very elegant, but takes some shift in thinking.

I don't remember such a reference, but I can't imagine a system in
which nil ISN'T falsy...
