[chuck-users] functions returning arrays

Hi Chuckists,

A question about arrays in Chuck: the manual briefly mentions "functions that have arrays as arguments or return type" but I can't seem to find an actual example of a function with an array as a return type.  Does anyone know if this works, or there is a way to make it work?

If I call the function below, for instance, I get a "NullPointerException: (array access)" when I do anything with the result:

fun float[] t(float x,float nn[]) {
    float rr[];
    for(0 => int n;n<nn.size();n++) {
        nn[n] + x => rr[n];
    return rr;

Yours truly,
