Polymorphism and Dispatch Semantics: Pitfalls

Pitfalls and red flags

• Calling non-virtual methods through base handles and expecting derived behavior.

• Downcasting without $cast checks before using derived-only members.

• Designing APIs that expose only derived types, eliminating polymorphic flexibility.

• Storing aliased handles in scoreboards without clear ownership or cloning policy.
