Simple import/export pairs that could just be included (most of these were to break up docs into their own pages):

- [ ] [system/exceptions](https://github.com/nim-lang/Nim/blob/96d6eee9bc33c22defb980fc0953c8e55f363ab2/lib/system.nim#L543-L544)

  - also imported in [rawquits](https://github.com/nim-lang/Nim/blob/96d6eee9bc33c22defb980fc0953c8e55f363ab2/lib/system/rawquits.nim#L1) but this import is unnecessary because rawquits is included immediately after ctypes in system
- [ ] [system/iterators](https://github.com/nim-lang/Nim/blob/96d6eee9bc33c22defb980fc0953c8e55f363ab2/lib/system.nim#L1735-L1736)
