Hello, I’ve read somewhere (but I cannot recall where) that there are “cheap” reflection methods and “expensive” reflection methods in Kotlin, do anyone know where may I find more information regarding that?

I think you may be referring to the invokedynamic API introduced in Java 7 and used in Java 8 to implement fast execution of lambdas. It’s a JVM feature that lets you invoke methods faster than with standard reflection, could be this you’ve read?

Sorry, it wasn’t that… It was something like lite reflection methods (not requiring you to import `reflect` library). Regarding that, do I need to import `reflect` to use something like `Type::field`? Thanks for sharing your thoughts :)

Sorry I’ve never heard anything like that. The only “lite” reflection I can think of is `java.lang.invoke`. If you’re referring to Kotlin specifically, from what you tell maybe you’re referring to <https://kotlinlang.org/docs/reference/reflection.html#function-references|function references>: depending on the usage you don’t need to import the reflect library (although it’s still reflection).
Instead, to manipulate stuff like `Type::field` yes, you need to import `kotlin-reflect` .
