Why is value of `_tokenApprovals` mapping a struct with one parameter instead simply an address? #475

Closed Lruquaf closed 1 year ago

Lruquaf commented 1 year ago 
struct TokenApprovalRef {
        address value;
}

// Mapping from token ID to approved address.
    mapping(uint256 => TokenApprovalRef) private _tokenApprovals;

This is a workaround for a old compiler bug.
