  "message": "Add a `FlexibleAlias` to `mypy_extensions` (#5436)\n\nCurrently there is no way to define generic type aliases that do not\r\ndepend on their type arguments or that are just directly a type\r\nvariable.\r\n\r\n`FlexibleAlias[T, typ]` creates a type that depends on `T` but that is\r\nexpanded to `typ` during type alias expansion.\r\n\r\nOne target use case for this is in creating conditionally defined type\r\naliases that depend on their argument under certain configurations but\r\nnot under others, for example:\r\n```\r\nif BOGUS:\r\n    Bogus \u003d FlexibleAlias[T, Any]\r\nelse:\r\n    Bogus \u003d FlexibleAlias[T, T]\r\n```\r\n",
