But Really, You Should Learn Smalltalk
summary
Demo uses a Pharo image and the Smalltalk workspace and inspector to edit live objects, run code instantly, and save whole system state. The talk shows 1-based arrays causing a null on index 1, walks through a quick test-driven cycle that creates a User class, adds accessors, and implements a canonical_email method, and demonstrates tests going red then green with immediate feedback. It emphasizes the live inspector where objects, stack frames, and code are inspected and modified on the fly.
