+  //
+  //   Examples where this is used include:
+  //     a += …;
+  //     import a from '…';
+  //   where a is the node to be checked.
+  //
+  // - checkLValPattern() shall be used if the syntactic construct supports

+  //   destructuring patterns. This is generally appropriate for constructs for
+  //   which the spec says

+  //   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+  //   > an ArrayLiteral and AssignmentTargetType of [the production] is not

+  //     const a = …;
+  //     try { … } catch (a) { … }
+  //   where a is the node to be checked.
