/ Specifies the kind of template name that an identifier refers to.
/ Be careful when changing this: this enumeration is used in diagnostics.
enum TemplateNameKind {
  / The name does not refer to a template.
  TNK_Non_template = 0,
  / The name refers to a function template or a set of overloaded
  / functions that includes at least one function template, or (in C++20)
  / refers to a set of non-template functions but is followed by a '<'.
  TNK_Function_template,
  / The name refers to a template whose specialization produces a
  / type. The template itself could be a class template, template
  / template parameter, or template alias.
  TNK_Type_template,
  / The name refers to a variable template whose specialization produces a
  / variable.
  TNK_Var_template,
  / The name refers to a dependent template name:
  / \code
  / template<typename MetaFun, typename T1, typename T2> struct apply2 {
  /   typedef typename MetaFun::template apply<T1, T2>::type type;
  / };
  / \endcode
  /
  / Here, "apply" is a dependent template name within the typename
  / specifier in the typedef. "apply" is a nested template, and
  / whether the template name is assumed to refer to a type template or a
  / function template depends on the context in which the template
  / name occurs.
  TNK_Dependent_template_name,
  / Lookup for the name failed, but we're assuming it was a template name
  / anyway. In C++20, this is mandatory in order to parse ADL-only function
  / template specialization calls.
  TNK_Undeclared_template,
  / The name refers to a concept.
  TNK_Concept_template,
};
