-// Acorn: Loose parser
-//
-// This module provides an alternative parser (`parse_dammit`) that
-// exposes that same interface as `parse`, 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 `parse_dammit`. 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.
