Far enough, since it's not possible to change the parameter inside the 
function anyway.

Question though, what happens with an array literal, example:

void foo(int[] a = [1, 2, 3])()
{
     auto b = a; // allocation ?
     auto c = a; // allocation ?
}

As far as I understand, if an array is declared as a manifest constant 
it will cause a new allocation for each time it's used.

enum a = [1, 2, 3];
auto b = a; // new allocation
auto c = a; // new allocation

What happens when an array literal is a default value for a template 
parameter?
