  "message": "Avoid repeatedly appending to yaml_implicit_resolvers\n\nRepeated calls to `resolve` can experience performance degredation, if\n`add_implicit_resolver` has been called with `first\u003dNone` (to add an\nimplicit resolver with an unspecified first character).\n\nFor example, every time `foo` is encountered, the \"wildcard implicit\nresolvers\" (with `first\u003dNone`) will be appended to the list of implicit\nresolvers for strings starting with `f`, which will normally be the\nresolver for booleans. The list `yaml_implicit_resolvers[\u0027f\u0027]` will keep\ngetting longer. The same behavior applies for any first-letter matches\nwith existing implicit resolvers.\n\nThis change avoids unintentionally mutating the lists in the class-level\ndict `yaml_implicit_resolvers` by looping through a temporary copy.\n\nFixes: #439\n",
