 When describing renames or replacements, `mod` refers to a 3rd-party package `mod` (no nMigen implementation provided), `.mod.item` refers to `nmigen.mod.item`, and "(import `.item`)" means that, while `item` is provided under `nmigen.mod.item`, it is aliased to, and should be imported from a shorter path for readability.
