Interesting. I guess that's why you'd have annotations on 
variables that are set at compile time; without those 
annotations, there would be no way to tell when the value is 
calculated, and with non-pure functions, that becomes important. 
In a way, requiring annotations is almost more elegant than 
requiring functional purity...
