* $Id$
*
* @note This header should be included after all types to be passed
* as template parameters to the TAO_Pseudo_{Var,Out}_T template
* classes have been declared. If the types in question are defined
* in another header, include that header before this one.
* @par
* Including other headers like "tao/CORBA_methods.h" here can cause
* circular dependency related problems when using compilers that
* lookup and bind non-dependent names in templates at definition time
* (i.e. while parsing the code) instead of at instantiation time.
*
* @todo Look into adding a template parameter to each of the
* templates in question that would be a trait containing the
* means for releasing references managed by the templates.
* Doing so should work around the non-dependent name issues in
* g++ 3.4, thus easing the requirement that this header be
* parsed last.
