We're working on a library to give access to that data, it's coming shortly, see https://youtrack.jetbrains.com/issue/KT-23198

04/19/2018, 7:57 AM@udalov will kotlin reflection be broken if names of the properties defined in the primary constructor are different from the according backing fields? e.g. as the result of obfuscation

04/19/2018, 8:06 AM@dstarcev yep!
@udalov will it also work at compile time (like with kapt), or only runtime?

@dstarcev can’t say for sure, but yeah, probably
@Eugenio both. It takes kotlin.Metadata’s content (ints, arrays of strings, etc) as an input

04/19/2018, 8:29 AM@Eugenio can I use https://github.com/Takhion/kotlin-metadata to parse kotlin.Metadata contents?

04/19/2018, 8:40 AM@dstarcev yes, in a few days I'll release v2 which will make it a lot easier (and documented 😅)
This not only does the parsing of the metadata, but uses the Java Annotation Processing APIs to derive type information, kinda like Kotlin reflection, but at compile time
It's still lower level though
Because you don't necesaarily have access to full types, the rules are slightly different

04/19/2018, 8:56 AM@Eugenio how do I do it with the current version? I have values of
kotlin.MetadataIf I am not mistaken, I need to get an instance of
