Scheme 3: Closures video
June 01, 2012 [Lisp, Programming Languages, Scheme, Tech, Videos]Series: Feel the cool, Basics, Closures, Recursion, Quotation, Lambda, Macros.
Continuing the series on Scheme, this video describes an important feature of functions in Scheme: closures. Closures allow functions to carry their "environment" around with them, and even change it later. This allows all kinds of exciting things, including implementing something similar to classes in other languages.
