   7    |          borrowed value does not live long enough
   8    |          a temporary with access to the borrow is created here ...
   9 LL |     };
  10    |     -- ... and the borrow might be used here, when that temporary is dropped and runs the destructor for type `Ref<'_, i32>`
  11    |     |
  12    |     `*a` dropped here while still borrowed
  13    |
  14    = note: the temporary is part of an expression at the end of a block;
  15            consider forcing this temporary to be dropped sooner, before the block's local variables are dropped
  16 help: for example, you could save the expression's value in a new local variable `x` and then make `x` be the expression at the end of the block
