By implementing it, I found some corner cases. How should these behave?

int f1(int a, double=10) { return 1; }
int f1(int a, string="") { return 2; }

int f2(T:int)(T b, double=10) { return 1; }
int f2(T:int)(T b, string="") { return 2; }

// vs deduced parameter
int f3(int a) { return 1; }
int f3(T)(T b) { return 2; }

// vs specialized parameter
int f4(int a) { return 1; }
int f4(T:int)(T b) { return 2; }

// vs deduced parameter + template constraint (1)
int f5(int a) { return 1; }
int f5(T)(T b) if (is(T == int)) { return 2; }

// vs deduced parameter + template constraint (2)
int f6(int a) { return 1; }
int f6(T)(T b) if (is(T : int)) { return 2; }

void main()
{
    f1(1);  // ambiguous error
    f1(1L); // ambiguous error

    f2(1);  // ambiguous error
    f2(1L); // ambiguous error

    f3(1);  // ?
    f3(1L); // ?

    f4(1);  // ?
    f4(1L); // ?

    f5(1);  // ?
    f5(1L); // ?

    f6(1);  // ?
    f6(1L); // ?
}
