The Token's value is described as being a in the attribute list: 460a221923/lark-stubs/lexer.pyi (L84) and as `Any` in `__init__` parameters: 460a221923/lark-stubs/lexer.pyi (L91) Yet one of the recipes, [Use a transformer to parse integer tokens](https://github.com/lark-parser/lark/blob/master/docs/recipes.md#use-a-transformer-to-parse-integer-tokens), recommends to set it to other types. So IIUC, `Any` is the correct one.
