if you expect it to work like python and being able to just omit b to get the defaults, then it's not automatic
you can however create the representation of the function with just a and use default value for b inside
like this:

int test(int a;int b)
{
    return a+b;
} 
int test(int a)
{
    int b = 2;
    return test(a, b);
} 

printf("%g\n", test(1)); // returns 3 (1 + default 2)
printf("%g\n", test(1,1)); // returns 2 (1 + 1)

noise_surf(vector clr = {1,1,1}; float frequency = 1;
           export vector nml = {0,0,0})
{
    Cf = clr * (float(noise(frequency * P)) + 0.5) * diffuse(normalize(N));
    nml = normalize(N)*0.5 + 0.5;
}
