Is .NET Native available on other platforms than Windows?  Mono 
seems to perform less well...

Not only managed, but UI-tweaking is better done in a language 
that doesn't require compilation, with hot reload (changes are 
visible in the running application without closing it first).

IMO, right now there are too many similar-looking languages. 
Whoever stands out for some very specific use scenarios gain

I found it a bit interesting that the Swift Server WG has 2 
people from IBM on board, maybe they see it as an alternative to 
Java with lower memory footprint (no GC). I wish I knew why they 
think Swift would be a good solution on the server.
