Python, for example, has a list type (mutable), and a tuple type (immutable). Swift could simply adopt the same thing and use `(1, 2, 3)` for immutable arrays and `[1, 2, 3]` for mutable arrays. It would break backwards compatibility but it is a beta.
Every other language (Ruby, Python, PHP, Javascript, for example) that uses `[]` as syntax for arrays always uses it as a mutable array type. I don't see why Swift shouldn't do the same, and provide a separate type and possibly new syntax for the immutable version.
