- Issues
- add: `IndexOf`, `LastIndexOf` and `IndicesOf` types
- `Nullish`/`Nilable` type (like `Partial`, but accepts null)
- Is it safe to use these types instead of the built-in ones everywhere?
- Make `CamelCasedPropertiesDeep` preserve leading underscores
- SetOptionalDeep
- `DeepValuesOf`
- `ArraySlice` should wrap around for `-T['length'] < Start/End < 0`
- Proposal: `ConditionalPaths`
- Add `ArrayExclude` type
- Paths should handle Record types with arbitrary string keys
