Can parameter pack function arguments be defaulted?

Question

This is a point about which gcc 4.9.2 and clang 3.5.2 are in sharp disagreement. The program:

template
int foo(int i = 0, Ts &&         


        

Answer 1

A Kerrek SB says, it's not possible. What you could do, instead, is using a std::tuple

template 
void foo( std::tuple t = std::tuple(0) )
{}
