/////////////////// Input file /////////////////////////////////////////
// ARM 9.7 Nested Class Declaration.

// From AT&T Annotated C++ Reference Manual, 9.7:
// "Except by using explicit pointers, references, and object names, 
// declarations in a nested class can use only type names, static members, 
// and enumerations from the enclosing class."

// This is an example from ARM $9.7.
