    Description

      I would strongly suggest implementing the below change. I used visual studio to profile an application that was hanging while loading a settings file while also processing many updates from a backend process. The profile indicated that the at function called here was taking up nearly 40% of the runtime of the application. After making the below change, everything loaded without any visible delay. It looks like this is a huge bottleneck and it is completely unnecessary.
