Metacircular evaluator, implementing the environment?

Your question could be a teensy bit more specific, but I believe I understand it.

To understand how this works, first of all you have to understand that the variable initial-env will point to the first frame of the environment, and this reference is never modified. The environment itself is a list of frames, and each frame is a pair of lists, the car of the first frame is the head of the list of variables, and the cdr of the first frame is the head of the list of values.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
