+### Bug fixes

   // Acorn: Loose parser
+  //
+  // This module provides an alternative parser that exposes that same
+  // interface as the main module's `parse` function, but will try to
+  // parse anything as JavaScript, repairing syntax error the best it
+  // can. There are circumstances in which it will raise an error and
+  // give up, but they are very rare. The resulting AST will be a mostly
+  // valid JavaScript AST (as per the [Mozilla parser API][api], except
+  // that:
+  //
+  // - Return outside functions is allowed
+  //
+  // - Label consistency (no conflicts, break only to existing labels)
+  //   is not enforced.
+  //
+  // - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+  //   the parser got too confused to return anything meaningful.
+  //
+  // [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+  //
+  // The expected use for this is to *first* try `acorn.parse`, and only
+  // if that fails switch to the loose parser. The loose parser might
+  // parse badly indented code incorrectly, so **don't** use it as your
+  // default parser.
+  //
+  // Quite a lot of acorn.js is duplicated here. The alternative was to
+  // add a *lot* of extra cruft to that file, making it less readable
+  // and slower. Copying and editing the code allowed me to make
+  // invasive changes and simplifications without creating a complicated
+  // tangle.
