Call C variadic function from D variadic function

[mw]

Just a observation, from the questions & answers in this thread 
and mine[1]: I think meta-programming in D is somehow like C++, 
it starts becoming a baroque language. The language is complex 
enough that there may be ways to get things done, but it's just 
quite difficult for ordinary users to find *THE* way.
