Macros vs Generics
| Dimension | Macros | Generics |
|---|---|---|
| Flexibility | Code transformation | Type abstraction |
| Compile cost | Incremental-friendly | Monomorphization overhead |
| Error messages | Can be cryptic | Clear |
| Debugging | Debug expanded code | Direct debugging |
| Use case | Reduce boilerplate | Generic algorithms |
