+/// Simple wrapper around std::function<void(raw_ostream&)>.
+/// This class is useful to construct print helpers for raw_ostream.
+///
+/// Example:
+/// Printable PrintRegister(unsigned Register) {
+/// return Printable([Register](raw_ostream &OS) {
+/// OS << getRegisterName(Register);
+/// }
+/// }
+/// ... OS << PrintRegister(Register); ...
+///
+/// Implementation note: Ideally this would just be a typedef, but doing so
+/// leads to operator << being ambiguous as function has matching constructors
+/// in some STL versions. I have seen the problem on gcc 4.6 libstdc++ and
+/// microsoft STL.
