Detailed Description

A forward-reference to a template argument that was not known at the point where the template parameter name was parsed in a mangling.

This is created when demangling the name of a specialization of a conversion function template:

struct A {
  template<typename T> operator T*();
};

When demangling a specialization of the conversion function template, we encounter the name of the template (including the T) before we reach the template argument list, so we cannot substitute the parameter name for the corresponding argument while parsing. Instead, we create a ForwardTemplateReference node that is resolved after we parse the template arguments.
