BundleDelegate.kt

Hello, I made this a few weeks ago and I just wanted to get some feedback on the implementation and maybe on the usefulness/syntax/design of its use?

I’m sure it can be extrapolated, but the usage looks something like
```val myBundleString: String by BundleDelegate.of(MY_BUNDLE_STRING_KEY)```

I think you can use:
```return extras.get(key)?.let { clazz.cast(it) } ?: throw Exception("Key does not exist in bundle.")```
This will throw a `ClassCastException` if the value is not `clazz` , and you don't have an unchecked cast.

Thanks! That’s a good point! I didn’t think to fall back on the built in `ClassCastException`

I feel like you could do this entirely with lazy, assuming you are inside of an `Activity`

```inline fun &lt;reified T&gt; Activity.fromBundle(key: String) = lazy {
    intent.extras[key] as? T ?: throw Exception("Key does not exist in bundle") 
}```

Interesting. I’ll have to toy with it. That’s a much cleaner approach, but I feel like some of the debugging fidelity is lost in the brevity.
