Make the API easy?
- Copy on Write to avoid copies at runtime
- Can we do it at compile time?
- Let tools get const and references right
- Warn about unnecessary copies
- Clang can help here
- need real examples
Make changes easy
- API changes are expensive
- API looks outdated if not adapted to current paradigms (legacy code)
- How can we make them easy
- How can Clang help here
Clang Query
- Think about it as SQL for the AST
- Makes big changes much cheaper and secure

- Run refactorings overnight for expansive refactorings
