It uses an emulation on compilers that dont support "native typeof". So that it can be used anyway. Now, if the compilers become less buggy, then we'll have to fix lots of code because it became an idiom relying on a bug-feature, since there isnt any workaround for a conforming compiler.
I think when compilers will be less buggy as for this trick, the standard will describe template friends. Otherwise, why all compilers noted in article has the same bug? Anyway, I provided the other solution based on macros. It is not so pretty, but standard. I also remember that Mayers has some solution with pure virtual method, I will try to find out. Thank you for you interest and time taken to read discussion. -- Vladislav Lazarenko
