Workaround:

private mixin template genToString()
{
    override string toString()
    {
        import std.array;
        import std.conv;
        import std.string;

        Appender!(string[]) result;

        foreach (val; this.tupleof)
        {
            result ~= to!string(val);
        }

        return format("%s(%s)", __traits(identifier, typeof(this)), 
                                result.data.join(", "));
    }
}

class C
{
    int x, y;
    mixin genToString;
}
