+Note that, for `.call`, we use `grep` to exclude
+several irrelevant occurrences of `.call`
+either within comments or from transpiled code.
+We err on the side of false exclusions.

+| `[^a-zA-Z][A-Z][a-zA-Z0-9_$]*\.call\( *this` | Constructor call obsoleted by `super`. See note. |
+| `_super\.call`                               | Babel-transpiled `super()` artifact.             |
+| `_super\.prototype\.`                        | Babel-transpiled `super.fn()` artifact.          |
+| `_objectWithoutProperties`                   | Babel-transpiled `...` artifact.                 |
+| `_getPrototypeOf`                            | Babel artifact.                                  |
+| `_possibleConstructorReturn`                 | Babel artifact.                                                |
+| `__super__`                                  | CoffeeScript artifact.                           |
+| `WEBPACK VAR INJECTION`                      | Webpack artifact.                                |
+| `\.hasOwnProperty\.call`                     | Obsoleted by `Object.has`.                       |
+
+These excluded patterns were determined
+by an independent investigator ([Scott Jamison][]),
+after manually reviewing the first 10,000 occurrences of `.call` in the dataset
+for why each occurrence occurred.
+
+The excluded `[^a-zA-Z][A-Z][a-zA-Z0-9_$]*\.call\( *this`
+pattern deserves a special note.
+This pattern matches any capitalized identifier followed by `.call(this`.
+We exclude any such occurrences because any capitalized identifier
+likely refers to a constructor,
+and using `.call` on a constructor is a pattern
+that has largely been obviated by `class` and `super` syntax.
+It is likely that this pattern erroneously excludes many legitimate uses
+of `.call` from our count, but this bias against `.call` is acceptable
+for the purposes of rough comparison.
