(piqi author here) There's a better way to handle names that conflict with OCaml keywords. Instead of using sed, you can add an extension module named riak_kv.ocaml.piqi with the following lines:

.include [ .module riak_kv ]
.extend [
    (.field RpbListKeysResp.done RpbMapRedResp.done)
    .with.ocaml-name "isdone"
]

This module will be included automatically by piqic ocaml and it will add OCaml-specific names to the existing definitions.

The complete example is available here. Note that it requires the latest version from "dev" branch.

@alavrik great, thank you! I will give it a try.
