Really, in the end, that is up to the error. In *most* cases it is probably best to return the error to the user, but there can be cases, where things just go absolutely wrong that a die isn't a bad idea (and can still be trapped by eval). But probably best is to return errors, and possibly have an option the user can set on whether they want errors to be fatal or not.
