T hinking about a perfect structure for a perfect environment, each symbol representing many possibilities, each key has it’s own purpose and behavior in that context. The only limitations is the scope of the created structures. Lisp had defined a style in programming, with new possibilities for problem solving that takes the programmer out of the box, and brings a new point of view. But finally it is only an interpretation, a translation between human and machine, we may give sense to our perception by the usage of language and writing, this perception can be very complex or very simple, it can always depend on the observer and the given context… for example hardware, only understands voltage, the abstraction of a programming language goes into the process of becoming machine language, which are kind of voltage instructions for the millions of transistors inside a CPU, programming language has been limited by this context, the limitations are hardware dependent. New approaches with
