Just thought it would be nice to give a heads up about Apple's plans to
replace Objective-C in the long run.
The language was presented today at the WWDC Keynote, looks like Ruby,
uses ARC alongside the Objective-C runtime.

It also has a nice REPL experience, similar to Python's worksheets in
IPython.

I like how the lambdas can omit the parameters then reference them by
special $0, $1, etc (e.g., { $0 < $1 }). It reminds me of our string
lambdas ("a < b") in brevity without the hacky feel those had. As much
as I like the new lambda syntax I still miss how short string lambdas
could be.
arr.sort!"a < b"();
arr.sort!((a, b) => a < b);
Maybe something like...
arr.sort!( => $0 < $1 )
...could be supported. Not a huge improvement but I like it anyway.
I think just $0 < $1 could infer the fact that it is a lambda, as this is
not currently valid syntax.
I would like that too.
