// NonZero returns a T set to some appropriate nonzero value:
//   - Values of basic type are set to an arbitrary non-zero value.
//   - Struct fields are set to a non-zero value.
//   - Array indices are set to a non-zero value.
//   - Pointers point to a non-zero value.
//   - Maps and slices are given a non-zero element.
//   - Chan, Func, Interface, UnsafePointer are all unsupported.

// NonZero breaks cycles by returning a zero value for recursive types.
