  "message": "Look at local sets with casts in OptimizeCasts.\n\nFor instance, the below\n(local.set $a (ref.cast .. (local.get $ref)))\n(local.get $a)\n\nCan be converted to\n(local.set $a (local.tee $temp (ref.cast .. (local.get $ref))))\n(local.get $temp)\n\nCurrently, this change only applies the optimization if the\nimmediate child of the local.set is a cast and cannot look through\nother operations. This is added as a TODO.\n",
