Cortically Magnified

In this post, I’ll summarize what I’ve learned from an attempt to gain a deeper understanding of two important concepts in programming: Python’s generators and Scheme’s continuation. The aim is not to teach Python or Scheme programming. Rather, what I want to do is to demonstrate that generators are special cases of a much more powerful construct - continuations. Continuations allow programmers to invent new control structures, and it is the foundation upon which iterators, generators, coroutines, and many other useful constructs can be built.
