Learning objectives

What you should understand

  1. Replace runtime dispatch only where variants are known
  2. Constrain templates with readable concepts
  3. Verify devirtualization and code-size cost

Lab

Hands-on exercise

Compare virtual, variant and concept-based handlers.

Deliverable

Evidence of completion
