Structural Pattern Matching in Python
summary
Concrete walkthrough of Python structural pattern matching shows match/case with wildcard _ and sequence patterns used to implement CLI-style command parsing where the first token selects behavior and the rest pack via a starred capture. It demonstrates literal, capture, OR and as patterns, guards (if), class patterns for dataclasses and classes using __match_args to control attribute order, enum value matching, dict key matching with **rest, and type checks using builtins like str — all examples compile and behave as described.
