This is agains 2.037.


void main() {
    float[2] a,b,c;
    a = [8.33, 7.11];
    b = [2.1, 3.1];
    double[2] d = [2.11, 3.11];
    int[2] e = [4,5];
    double[2] f;

// this should work
    //c[] = a[] ^^ b[]; // Error: float[] ^^ float[] is not supported
    //f[] = d[] ^^ d[]; // Error: double[] ^^ double[] is not supported

// just like
    c[] = a[] * c[]; // works

// if possible this also
    //c[] = 2.0f ^^ b[]; // Error: float ^^ float[] is not supported
    //c[] = a[] ^^ 2.0f; // Error: float[] ^^ float is not supported
    //f[] = d[] ^^ 2.0; // Error: double[] ^^ double is not supported
    //f[] = 2.0 ^^ d[]; // Error: double ^^ double[] is not supported

// and then this also (relevant opPow is working).
    //c[] = a[] ^^ e[]; // Error: float[] ^^ int[] is not supported
    //f[] = d[] ^^ e[]; // Error: double[] ^^ int[] is not supported
    //c[] = a[] ^^ 2; // Error: float[] ^^ int is not supported
    //f[] = d[] ^^ 2; // Error: double[] ^^ int is not supported

// and eventually this also, but this part involves mixed types,
// and there is no opPow(double,float)
    //c[] = 2.0 ^^ b[]; // Error: double ^^ float[] is not supported
    //f[] = d[] ^^ a[]; // Error: double[] ^^ float[] is not supported
// or opPow(float,double),
    //f[] = a[] ^^ 2.0; // Error: float[] ^^ double is not supported
    //f[] = a[] ^^ d[]; // Error: float[] ^^ double[] is not supported

// similary this doesnt work currently
    //c[] = a[] * d[]; // Error: incompatible types for ((a[]) * (e[])):
'float[]' and 'double[]'
    //c[] = a[] * e[]; // Error: incompatible types for ((a[]) * (e[])):
'float[]' and 'int[]'
}


btw. also this in opPow doesnt work

 float pi = 3.14;
 float x = pi ^^ 2.0;

one needs explicitly write 2.0f (this is because std.math.pow have only one F
template parameter, and compiler doesn't know which to infer).
