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.

My thoughts while browsing the site:
- function-leve type inference much like Rust
- no constness in the type-system (I like it)
- class are reference types, structs are values types, much like
D and C#
- runtime dispacthed OO interfaces called "protocols". Blend the
difference between runtime or compile-time polymorphism. Classes,
structs and enums can implement a protocol. Available as first
class runtime values, so the protocol dispatch will be slow like
in Golang.
- enumerations are much like Ocaml ADT, can be parameterized by a
tuple of values, value types, recursive definitions
- worrying focus on properties.
- strange closure syntax
- optional chaining, another anti-feature in my eyes
- normal arithmetic operator throw a trap on integer overflow
(!). This must be incredibly slow.
- looks like Array is a fat slice to a reference-counted array
- operator overloading is in, supercharged with custom operator,
custom precedence (!?)
- builtin tuples syntax
- break with C integer promotion, like Rust.
- I haven't seen pointers
- convenience is a keyword!
