The "generics" feature of Carbon is a large design effort that needs to be broken up into manageable steps. The first thing we need is a high-level goals document. The goals here reflect the desirable properties that we have discovered as part of considering several alternative generics designs:
- Use cases:
- Generic programming
- Upgrade path from C++ abstract interfaces
- Dependency injection
- Generics instead of open overloading and ADL
- Performance
- Better compiler experience
- Encapsulation
- Predictability
- Dispatch control
- Upgrade path from templates
- Coherence
- No novel name lookup
- Learn from others
- Interfaces are nominal
- Interop and evolution
- Bridge for C++ customization points
Goals are summarized in [this presentation](https://docs.google.com/presentation/d/12yGyu5Pvdag7CJp-_yLVkmbhyvuRIilBTNlkO0LKaHo/edit?usp=sharing&resourcekey=0-JB9yrUO4-6J8-zzGhnIyNg).
