Type Hints · interview question
What is the clearest sign that code around protocols should be refactored?
Multiple choiceMediumchapter-10-curatedpremiumtype-hintsprotocols
Answer and explanation
Correct answer
D. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Use protocols when the code depends on a capability or method set rather than on one specific implementation.
