  "message": "bazel syntax: generalize Concatter to HasBinary, for binary operators\n\nA Starlark value that implements HasBinary may define its own\nsemantics for binary operators such as x+y. See HasBinary for details.\n\nThis brings us a step closer to moving Selector{List,Value} to lib.packages.\n\nAlso:\n- remove the Location parameter from the operator method.\n  This API simplification causes a minor usability regression:\n  SkylarkInfo instances created by x+y will no longer record the\n  location of the plus operator.\n- make the control tree for binary operator cases shallower\n  (that is, avoid unnecessary re-tests of instanceof),\n  with a single fall-through.\n- The specialized error message for \u0027in\u0027 is no longer feasible\n  as the set of valid operand types is no longer closed.\n- Simplify arithmetic division, borrowing from go.starlark.net.\n\nThis is a breaking API change for Copybara.\n\nPiperOrigin-RevId: 291726807\n",
