Commonly assumed
A class extending Equatable automatically formats its fields in toString() output by iterating over its overridden props.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- if (User('alice').toString() != 'User') throw 'toString defaults to just the class name, not the formatted props';
