can't swap absl::FixedArray about abseil-cpp HOT 2 OPEN

I'm not sure the typical use cases for FixedArray are cases for which having a swap method makes sense. FixedArray is usually used for putting a small array on the stack, but with an extent determined at runtime. How does swapping two FixedArrays of differing sizes that are backed with stack memory work? I suspect if you are trying to swap, absl::InlinedVector is a better choice. Can you describe the use case?

My use case is that I need a lot of usually very small arrays which don't need to be resizable and I thought that absl::FixedArray would be a nice fit for that. absl::InlinedVector has the extra capacity that I don't need. But since you can't swap an absl::FixedArray you can't really use that thing for pretty much anything besides local variables.
