C++ is complex, it is obvious why it is harder to learn.
Other languages don't have this mostly because they are not as powerful (i  
don't think i need to explain this).
And this is what i mean, the reason its complexity, not the building  
blocks we are talking about. (again, i don't believe this syntax has  
anything to do with C++ being complex).
