{
  "content": "  The error message \"expected `vars`, got ident `a`\" suggests that the parser is expecting a `vars` keyword, but it found an identifier `a` instead.\n\nThe `vars` keyword is used to declare a list of variables in a `data` declaration. For example:\n```\ndata MyData = MyData {\n  a :: Int,\n  b :: String\n}\n```\nIn this example, `a` and `b` are declared as variables in the `MyData` data type.\n\nIt's possible that the parser is confused by the `a` identifier in the `data` declaration, and is expecting a `vars` keyword instead.\n\nTo fix this error, you can try adding a `vars` keyword before the `a` identifier, like this:\n```\ndata MyData = MyData {\n  vars a :: Int,\n  b :: String\n}\n```\nThis should tell the parser that `a` is a variable in the `MyData` data type, and it should be able to parse the rest of the code correctly.",
