Newer features in Objective C

[[[ To any NSA and FBI agents reading my email: please consider    ]]]
[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

GNU Objective C supports the features that Objective C had in 1989.
It would be nice to add the newer Objective C features.
Is anyone interested in doing that?
Please write to me personally if you sare intested in working on this.
