[swift-users] What novel features of Swift should I show off in an intro-to-Swift talk?

[Austin Zheng]

One possible topic might be support for COW value types. If you have the
time you could even demonstrate implementing something like a first-class
mini-BigNum type, complete with isUniquelyReferenced() and operator
overloading.
