What is the reason for remember() not using all the variables referenced by calculation as implicit keys by default? Wouldn't it result in more correct usage?
Thanks.

They don’t always need to be keys

And even if they did, it’s not possible to introspect the lambda to find all variables referenced without more custom compiler magic. You could use the result of the lambda, but then that’s equivalent to not using remember at all.

custom compiler magic

Yes, I would have expected more compiler magic 🙂
Something similar to what the compiler plugin does with derivedStateOf() .

The compiler plugin doesn’t do anything with derivedStateOf

Compose’s compiler plugin is ONLY used for making the @Composable annotation work
