  "message": "starlark: add debug API for Locals and FreeVars\n\nThis change adds the following new API to allow debugging tools\nand built-in functions access to the internals of Function values\nand call frames:\n\npackage starlark\n\ntype Binding struct {\n       Name string\n       Pos  syntax.Position\n}\n\nfunc (fr *frame) NumLocals() int\nfunc (fr *frame) Local(i int) (Binding, Value)\n\ntype DebugFrame interface {\n    ...\n    NumLocals() int\n    Local(i int) (Binding, Value)\n}\n\nfunc (fn *Function) NumFreeVars() int\nfunc (fn *Function) FreeVar(i int) (Binding, Value)\n\nThis is strictly a breaking change, but the changed functions\n(the Local methods) were previously documented as experimental.\nThe fix is straightforward.\n\nAlso, a test of DebugFrame to write an \u0027env\u0027 function in\na similar vein to Python\u0027s \u0027dir\u0027 function.\n\nFixes #538\n",
