// Canonical, qualified type template
//----------------------------------------------------------------------------//
/// Represents a canonical, potentially-qualified type.
///
/// The CanQual template is a lightweight smart pointer that provides access
/// to the canonical representation of a type, where all typedefs and other
/// syntactic sugar has been eliminated. A CanQualType may also have various
/// qualifiers (const, volatile, restrict) attached to it.
///
/// The template type parameter @p T is one of the Type classes (PointerType,
/// BuiltinType, etc.). The type stored within @c CanQual<T> will be of that
/// type (or some subclass of that type). The typedef @c CanQualType is just
/// a shorthand for @c CanQual<Type>.
///
/// An instance of @c CanQual<T> can be implicitly converted to a
/// @c CanQual<U> when T is derived from U, which essentially provides an
/// implicit upcast. For example, @c CanQual<LValueReferenceType> can be
/// converted to @c CanQual<ReferenceType>. Note that any @c CanQual type can
/// be implicitly converted to a QualType, but the reverse operation requires
/// a call to ASTContext::getCanonicalType().
