Interesting way of using the new variadic templates to create a variadic print() function.

variadic_print.cpp

// Compile with: g++  -std=c++11 variadic_print.cpp -o variadic_print
#include <iostream>

//  No argument case
void print() {}


//  Recursive Variadic Template
template <typename HEAD, typename ... TAIL>
void print(const HEAD& head, const TAIL& ... tail) {
  std::cout << head << std::endl;
  print(tail...);
}


int main(){

  print(1, 2, 3, 3.14159, "Slick use of templates");
  return 0;
}

Fun, but for each call with n arguments it actually generates n separate but nearly identical templated print<> functions, even at -O3.

ie

0x100000670    1 166          sym.voidprint_int_int_int_double_char_23___intconst__intconst__intconst__doubleconst__charconst____23__
0x100000730    1 155          sym.voidprint_int_int_double_char_23___intconst__intconst__doubleconst__charconst____23__
0x1000007e0    1 148          sym.voidprint_int_double_char_23___intconst__doubleconst__charconst____23__
0x100000890    1 137          sym.voidprint_double_char_23___doubleconst__charconst____23__
0x100000930    1 135          sym.voidprint_char_23___charconst____23__

Not practical, but I still thought it was cute.
