The intention is very clear: only read the selected columns
from the csv, and for any other fields of class Layout, just
ignore (with the default D .init value).
Why don't you do this? For example you can try the following?
```d
import std.csv, std.math.algebraic : abs;
string str = "a,b,c\nHello,65,63.63\n➊➋➂❹,123,3673.562";
struct Layout
{
int value;
double other;
string name;
}
You didn't get my question, please add:
```
int extra_field; // un-comment to see the error
```
to the struct, then you will see the error.
