// A regression test for dart2js generating illegal JavaScript code
// dynamically in non-csp mode.  The name of the field "defaultValue"
// in JavaScript is "default".  This meant that dart2js would create a
// constructor function that looked like this:
//
// function TrackElement(default) { this.default = default; }
