transitions

States and transitions are first-class objects, making code self-documenting and maintainable, as demonstrated in the NarcolepticSuperhero example with clear state definitions and transitions.

Supports before, after, enter, and exit callbacks for fine-grained control over state changes, detailed in sections like 'Callbacks' and 'Transition callbacks' with examples like update_journal and change_into_super_secret_costume.

Enables nesting of states for complex workflows via the HSM extension, facilitating reuse and organization, as mentioned in the 'Hierarchical State Machine' extension section.

Can generate diagrams for state machines to aid debugging and documentation, shown in the 'Diagrams' extension with examples like the batman diagram in the Quickstart.

Offers multiple ways to bind machines to models, including inheritance or standalone instances, as detailed in 'Alternative initialization patterns' with examples like Machine(model=lump) or class Matter(Machine).
