> type inference There is a JEP (286) for that. Personally I consider it highly harmful. I regularly read C# source of unknown libraries outside of an IDE (Like on Github) and very often I don't have the faintest clue what type a var holds even it is just a type well known to me, making navigation of that code very difficult. > lazy properties This looks interesting. I don't think Java will ever offer it though. > Dynamic Why would you want to kill the static type safety we cherish so much? I only ever had to use dynamic in C# when working with horrible legacy APIs. Besides that, interface proxies and cglib proxies (bytecode manipulated classes) are heavily used in Java frameworks and do the delegation you talk about. > Structs Value types will be available in Java 10. (JEP 169: "Provide JVM infrastructure for working with immutable and reference-free objects, in support of efficient by-value computation with non-primitive types.")
