Hi, beginner question: What's the meaning of '+' in Jetpack Compose? For example in `+vectorResource(R.drawable.ic_face_primary_24dp)`. When it should be used and when not? Couldn't find it in the tutorial or ADS talks.

It’s to do with the ‘effect’ system and it’s getting removed

Right now it’s an easy way to convert from an effect to something you can work with iirc

I was told today `+` is analogous to `@Model` on the class — it tells Compose to treat this call different than simple function calls

`+` is kind of like an operator invoke for effects. The functions that return effects just return an object for the effect and the `+` says, "add it into the composition here"

and yeah they're being made to behave more like composable functions in the future
