Add babel legacy decorators support

[EugenePisotsky]

Inversify decorators don't work with Babel, maybe because of different specification:

Possible Solution

Here's an example of working with Babel decorator, I suppose it works because it returns the descriptor (assign doesn't work):

function lazyInject(identifier?) {
    return (protoOrDescriptor, name?): any => ({
        configurable: true,
        enumerable: true,
        get: () => {
            return container.get(identifier);
        },
        set: () => void 0,
    });
}

Context

React Native 0.59 updated their bundler version and now it doesn't support the latest react-native-typescript-transformer. The problem is that developers of react-native-typescript-transformer are not going to keep supporting it and also recommend developers switching to Babel. Now it's impossible to use InversifyJS with ReactNative since 0.59 at all, as Babel is the only option we can use.

Is there an update on this topic? I'm facing the same issue right know with a RN application and I don't know how to workaround this problem even after following #1007. Is the only option to use Inversify without decorators? Like in vanilla JS

In my project, I had issues caused by babel and inversify @inject directive usage. I used Metro server (not Expo). I believe the solution must be similar for both. I couldn't find a standalone solution. After much trial and error, I solved it. I hope my solution will save someone a lot of time.

Hey all, I undestand your concerns here. Given the existence of babel-plugin-transform-typescript-metadata I don't think we don't need to provide babel decorators.

I'm closing the issue beliving the amount of different workarounds and this StackOverflow answer relying on the babel plugin are more than enough.

Feel free to comment on this issue if you think there's something left.
