 //
 // This file implements stripping symbols out of symbol tables.
 //
 // Specifically, this allows you to strip all of the symbols out of:
-//   * A method
-//   * All methods in a module
-//   * All symbols in a module (all method symbols + all module scope symbols)
+//   * A function
+//   * All functions in a module
+//   * All symbols in a module (all function symbols + all module scope symbols)
 //
 // Notice that:
 //   * This pass makes code much less readable, so it should only be used in
