Thanks for the code suggestion although it still doesn't fix
the bug. I am curious as to what those brackets do as well.
Okay, my bad for writing the wrong code, the correct one is:
```d
foreach (BoardSize boardSizeIter; arr) (Boardsize boardSize){ //
notice the brackets and I changed the variable names a little
Button button = new Button();
button.text = format("%sx%s", boardSize[0], boardSize[1]);
button.onButtonClick = {
eventHandler.settingsWindow_onBoardSizeButtonClick(boardSize);
};
button.onButtonClick();
_boardSizeRow.addChild(button);
}(boardSizeIter) // notice the brackets and that I changed the
name of you first foreach argument
```
This will do the same thing as HS Teoh and Tsbockman's code did :
create a copy of the value that is currently present in one
particular iteration of the `foreach` by creating a function
literal that takes your `struct` as a paramter. This works
because structs are value types, so passing it to the function
creates a copy.
