The Road to Pattern Matching in Python
summary
Explains why pattern matching becomes a new statement with match and case are soft keywords, shows the concrete one-line area example that both selects branch and extracts radius/width/height, gives deterministic binding rules — e.g. all simple names are binding targets and each alternative must bind the same variables exactly once — and sketches extensibility via custom match methods so classes can expose alternative views of objects.
