(In Unity, Javascript is compiled using Boo. The error messages reported for a Javascript script in Unity come from the Boo compiler, so this is a good reference. Please don't trivially copy the error message across, just use them when you see community members asking for help on specific errors. BCE0133 should never appear, for example.)
