oh yeah i missed that part.

D basically can't do that exactly, but if you pass the args as 
template things directly you can do this:

---
void main(string[] args) {
         int a;
         int b = 34;
         dbg!(a, b); // notice the !
}

void dbg(Args...)(size_t line = __LINE__) {
         import std.stdio;

         write("#", line, ": ");
         foreach(idx, alias arg; Args) {
                 if(idx) write(", ");
                 write(arg.stringof, " = ", arg);
         }
         writeln();
}
---

#4: a = 0, b = 34


Or reformat the output however you want.
