If i do this:
________________________________
>import std.csv;
import std.string;
import std.stdio;

struct Data{
    public:
        string field1;
        string field2;

    @property void field3( string field ){
        _field3 = field.split(";");
    }

    @property string field3( ){
        string result;
        foreach( item; _field3 )
            result ~= " %s;".format( item );
        return result;
    }

    @property attributes(){
        return  _field3;
    }

    private:
        string[] _field3;
}

void main(){
    Data[] result;
    File f = File( "data.csv", "r" );
    foreach( char[] line; f.byLine() ){
        result ~= csvReader!Data(line, '\t').front;
    }
}
________________________________


Same result
