// This test concerns the identity of dependent types within the

// canonical type system, specifically focusing on the difference

// between members of the current instantiation and membmers of an
|
|
// unknown specialization. This considers C++ [temp.type], which
|
|
// specifies type equivalence within a template, and C++0x
|
|
// [temp.dep.type], which defines what it means to be a member of the
|
|
// current instantiation.
