Typescript `enum` from JSON string

Question

Is there any way to have a TypeScript enum compatible with strings from JSON?

For example:

enum Type { NEW, OLD }

interface Thing { type: Type }

I've been using converter functions as a stopgap. Hopefully this thread comes to a resolution: https://github.com/Microsoft/TypeScript/issues/1206

enum ErrorCode {
    Foo,
    Bar
}

interface Error {
    code: ErrorCode;
    message?: string;
}

function convertToError(obj: any): Error {
    let typed: Error = obj as Error;

    // Fix any enums
    typed.code = ErrorCode[typed.code.toString()];
    return typed;
}
