Consider this code: ```res let status = json ->optional(field("status", string, _), _) ->Option.mapOr(Status.Active, Status.fromString) ``` after formatting some superfluous parens are added: ```res let status = json ->(optional(field("status", string, _), _)) ->Option.mapOr(Status.Active, Status.fromString) ``` I tried some versions and it seems it was introduced with 11.1.1 [Playground link](https://rescript-lang.org/try?version=v11.1.4&module=esmodule&code=DYUwLgBAzmCGYFcoQLwCgKYgKygewDsMsBaAPjwAcwBLQ2YACgDMaRgATRgIhniW4AaaGABONAgHNhAfQCUsucUzkA8tToEAdAFtYlVaMYBlOIihaAggGNaANxDDT-C81F4dp8VKVA)
