Implements a global examine/ex command that shows detailed descriptions
of objects. Searches inventory first, then ground at player position.
Works with Things, Containers, and Mobs.
Verbs let any Object have interactive handlers players can trigger.
Uses @verb decorator to mark methods that auto-register on instantiation.
- Object._verbs dict stores verb name to async handler mapping
- Object.register_verb(), get_verb(), has_verb() API
- @verb decorator marks methods with _verb_name attribute
- __post_init__ scans for decorated methods and registers them
- find_object() helper searches inventory then ground by name/alias
- Bound methods stored in _verbs (self already bound)
- Works on Object and all subclasses (Thing, Entity, etc)
- 18 tests covering registration, lookup, decoration, inheritance
Object.move_to() handles containment transfer: removes from old location's
contents, updates location pointer and coordinates, adds to new location.
get/drop commands use move_to to transfer Things between zone and inventory.
Supports name and alias matching for item lookup.
Object provides name, location, x/y, contents reverse-lookup, and
can_accept() — the foundation for the containment tree that zones,
things, and inventory will build on.
