import std.stdio;

void main() {
    double[] foo = [1.0,2,3,4,5].dup;
    writeln(foo[] * 2.0);

}

Also note the following:

float[] a = [0.f, 0.5f, 1.0f, 1.5f, 2.0f, 2.5f];
float[] b = [0.f, 0.5f, 1.0f, 1.5f, 2.0f, 2.5f];

writeln(a[] * b[]); // compiles, but results in access violation
writeln(a[] + b[]); // array operation a[] + b[] not implemented
