		// 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
