Pre-C++11 I would agree. However availability of variadic args makes 
putting tags at the end harder than at the start. For me personally 
in my own code, I would prefer all tags to go at the front rather 
than some at the start and some at the end.

Ok, I'm being lazy, but it saves productivity in having to write 
Args&&... filters just to put tags at the end.

Unless you know of a better way?
