Build brief

You are turning the Type Hints module into a concrete artifact. Keep the scope small, make the behavior visible, and leave enough notes that another learner can understand the result.

Requirements

  • Use at least two ideas from Type Hints.
  • Keep the implementation small enough to explain in five minutes.
  • Add three test cases or examples that show normal and edge behavior.
  • Write a short reflection that explains what broke and how you fixed it.

Deliverables

  • A working implementation connected to Type Hints.
  • A short README-style explanation of usage and expected output.
  • A small set of examples or tests that prove the behavior.
