Hierarchy
Intuition
If you ever used lens optics' names will be quite familiar to you,
but for a Monocle user Tofu's naming may be confusing. The following table may clear things up:
| Monocle | tofu |
|---|---|
| Iso | Equivalent |
| Prism | Subset |
| Lens | Contains |
| Optional | Property |
| Traversal | Items |
| Getter | Extract |
| Fold | Folded |
| Setter | Update |
