import std.math;
void main() {
    double[3] a, b, c;
    b[] = a[] ^^ 2;         // OK
    c[] = (a[] + b[]) * 2;  // OK
    c[] = (a[] + b[]) ^^ 2; // Error
}


DMD 2.064 alpha gives:

test.d(6): Error: incompatible types for ((a[] + b[]) ^^ (cast(double)2)):
'double[]' and 'double'

(Another problem is that the exponent should not be converted to double.)
