 They must start with a "." or "/", similar to how they would be expressed in a shell.

+## Inherit statements
+
+An inherit statement can be used to _pull_ values out of a parent scope
+into the current one. Values are whitespace separated and the statement
+ends with a `;`.
+
+If an attribute set in parenthesis follows immediately after the `inherit`
+keyword, then values can also be pulled directly out of the given set.
+
+In a `let` block, inherit statements can also come before the values they
+reference, so long as they are in the same block.
+
+```
+let
+  inherit (set.values) name version;
+
+  set.values = {
+    name = "package";
+    version = "0.1.0";
+  };
+in
+{ inherit name version; }
