I thought you know Lisp? Now you are surprised that Lisp often looks up functions via symbols -> aka "late binding"? How can that be? That's one of the basic Lisp features. Next you can find out what optimizing compilers d

From what I see in your example, you invoke the form again. In Common Lisp you don't need that. You can stay in a computation and fix&resume from within.

I would propose to watch the linked Youtube video: https://www.youtube.com/watch?v=BMoHE96rh7w It's actually several people working on it. Yes, one can develop Lisp software with more than one person. ;-)

In Lisp (and similar) sometimes the term object is used, since it's not the variable that's important, but the data object which is returned from a function and which has an identity. A symbol has by definition an entity. A symbol
