Is there a way to get the address of the function that would be used in Implicit Function Template Instantiation?

Explicitly instantiating the template can result in a function 
that may be behaviorally identical but have a different address.

auto foo(T)(const T x) { return x; }

void main()
{
     const int a;
     assert(&foo!int !is &foo!(const int)); // The addresses are 
different.
     foo(a); // If I look in the object file I can see this uses 
foo!int.
     assert(&foo!(typeof(a)) !is &foo!int);
}
