-// Issue #62007: assigning over a const-index projection of an array
-// (in this case, `list[I] = n;`) should in theory be able to kill all borrows
-// of `list[0]`, so that `list[0]` could be borrowed on the next
-// iteration through the loop.
-//
-// Currently the compiler does not allow this. We may want to consider
-// loosening that restriction in the future. (However, doing so would
-// at *least* require T-lang team approval, and probably an RFC; e.g.
-// such loosening might make complicate the user's mental mode; it
-// also would make code more brittle in the face of refactorings that
-// replace constants with variables.
