I think Rust and D have seamless integration with C style ABIs. Swift is native on iOS. Haskel and OCaml have, as far as I understand, painful FFIs and a relatively heavy runtime so I wouldn't call them native.

edit: to be clear, using 'compiles to object code' as the definition of Native, is both a misuse of the word, and meaningless as it is a implementation detail that can change easily and bound to be obsolete quickly.

Try to write a GUI WIndows app, COM server, or service daemon in Rust and C#, then let me know which one is more native.

Bonus points if it is a UWP one.

I wouldn't want to be caught dead writing a GUI Windows app (I might do Qt if forced at gunpoint though), so I'm probably not the best person to test this :)
