__VA_ARGS__ is iso C99 (but ok not c++). The point is only that boost prefers iso C90, since it is much more widely supported.

I have some implementation question on your proposition : how will you detect that 'this' exist, that you are not inside a static function ? If you can do such a thing I am interested to know how you do it (because I did not find out myself) ?

My example is trickier than it looks, since it uses the defect 45 of the iso to allow private access for nested classes. This quite unfortunate since the defect 45 is only of statut DR instead of TC1 (which is required for being part of the standard).
