Currently `jscodeshit@0.13.1` choke on Flow's indexed access types. > Error: did not recognize object of type "IndexedAccessType" It should be "just" a matter of updating `recast`, which comes with `ast-types`. Support for `IndexedAccessType` was added as of `ast-types@0.15.0`. EDIT: as of today, both `recast@0.21` and `ast-types@0.15` are not published on the `latest` tag, but `next`. /cc @benjamn
