Practical Common Lisp
Google TechTalks
Peter Seibel's 2006 Google TechTalk on Practical Common Lisp, framed by the Sapir-Whorf hypothesis and Paul Graham's Blub paradox. It shows Lisp features such as condition restarts and its generic-function object system.
HN remembers it as the memorable explanation of restarts and multiple dispatch, referenced whenever those features come up.
