Ah, I know that feeling. I've been using C++ for about 4 years and I'm learning something new constantly. I find that as my programs get more complex, I become more willing to explore new features of the language, to see if they'd help. So I guess the best path to follow would be a on-a-need-to-know-basis-path. :)
But i do not know in which way i should proceed...that is what should learn, what path should i follow?
because i consider that i have not yet learned half of C++ and i do not really know what is ahead.
