Does anyone have recommendations on libraries/articles that covers annotation processing of properties and objects? Is there any way to utilize Kotlin Reflect from Element/TypeElement/etc?

You could probably make use of <https://github.com/Takhion/kotlin-metadata>. Zac Sweers gave a talk about AP at KotlinConf, talked a lot about that library.

Here are the slides at least. <https://speakerdeck.com/hzsweers/annotation-processing-in-a-kotlin-world>

Yeah, I'm excited for the conf videos to go up during the week

Arrow has a meta tool that gives you a full kotlin AST from type element with methods to transform whatever you need and delegates code generation to Kotlin Poet

The `@extension` and `ExtensionProcessor` are written with Arrow meta. <https://github.com/arrow-kt/arrow/blob/master/modules/meta/arrow-meta/src/main/java/arrow/meta/ast/ast.kt>

It also works with and integrates <@U0B85AN68>'s library which uses extensively to read the metadata that TypeElement lacks <https://github.com/arrow-kt/arrow/blob/master/modules/meta/arrow-meta/src/main/java/arrow/meta/encoder/jvm/TypeElementEncoder.kt#L37> and for any `TypeElement` you can get it's now an AST as a `Type` <https://github.com/arrow-kt/arrow/blob/master/modules/meta/arrow-meta/src/main/java/arrow/meta/encoder/jvm/TypeElementEncoder.kt#L424>

just need to override this method to generate code for any annotated types.
