…opy value. The key thing is that the move checker will not consider the explicit copy value to be a copy_value that can be rewritten, ensuring that any uses of the result of the explicit copy_value (consuming or other wise) are not checked. Similar to the _move operator I recently introduced, this is a transparent function so we can perform one level of specialization and thus at least be generic over all concrete types.
Just a thinko on my part.

Unhappily, I didn't clang-format this. So I just did that and now need to restart testing =---(. |

The way this works is that:
NOTE: I also noted in a different PR I did not make _move public. I did this in this PR as well so we can get both of these operators together. Thanks to @glessard for helping me to catch that!
