I think you're probably right, but what about

    class Layout
    {
        int value;
        double other;
        string name;
    }

struct Cache {
    Layout data;
    alias data this;
    int extra_field;  // un-comment to see the error

   static Cache opCall(Layout d) {
       Cache c;
       c.data = d;
       return c;
   }
} 

void main()
{
    import std.csv;
    import std.stdio: write, writeln, writef, writefln;
    import std.algorithm.comparison : equal;
    import std.algorithm : map;
    string text = "a,b,c\nHello,65,2.5\nWorld,123,7.5";

    auto records =
        text.csvReader!Layout(["b","c","a"])
       .map!(x => Cache(x)) ;  // Read only these column
    foreach (r; records) writeln(r.name);
}
