// emits diagnostic messages when it first creates a template instantiation, so
// subsequent uses of a template with the same arguments will not print the
// expected errors. This macro creates a type that shadows its corresponding
// type from an ancestor scope, but is distinct for the purposes of
// instantiating a template.
