is this::class.java.simpleName using reflection?

[Ruckus]

It doesn't use the Kotlin reflection library, but it does use reflection.

[matt tighe]

Is the reflection library in particular where the performance impacts are bad?

[Ruckus]

Performance impact is rarely about which particular features you use. It's all about how you use them.

[Ruckus]

Reflection can definitely be considered "slow" (relatively speaking), but unless you're doing something crazy in a hot loop, the overall performance impact will likely be negligible.

Try to cache them in a closure? For better performance
