Kotlin Meta and CT programming vs D

[Renato Athaydes]

I forgot to mention, Kotlin also has some features that rely on 
compiler plugins, like serialization: 
https://kotlinlang.org/docs/serialization.html#formats, usually 
done via Gradle plugins.

This would normally be done via reflection, as Google's JSON 
library for Java, Gson, does. But by having a compiler plugin, 
they generate source code at "compile time" which basically looks 
at the type declaration and generates custom-made handlers that 
can parse/write JSON for them.
