import std.format;
void main() {
    int[3] row;
    auto text = "10 20 30";
    formattedRead(text, "%(%d %)", row);
}


DMD 2.060alpha:

...\dmd2\src\phobos\std\format.d(555): Error: using * on an array is
deprecated; use *(_param_2).ptr instead
...\dmd2\src\phobos\std\format.d(566): Error: using * on an array is
deprecated; use *(_param_2).ptr instead
test.d(5): Error: template instance
std.format.formattedRead!(string,char,uint[3u]) error instantiating


Part inside formattedRead, that uses * three times:

        alias typeof(*args[0]) A;
        static if (isTuple!A)
        {
            foreach (i, T; A.Types)
            {
                (*args[0])[i] = unformatValue!(T)(r, spec);
                skipUnstoredFields();
            }
        }
        else
        {
            *args[0] = unformatValue!(A)(r, spec);

The bug is in your code.

void main() {
    int[3] row;
    auto text = "10 20 30";
  //formattedRead(text, "%(%d %)", row);   // bad
    formattedRead(text, "%(%d %)", &row);  // OK
}

Phobos should catch the error with a template constraint instead of showing confusing errors in the template body.
