  Json_spel_t.json_spel ->
  string ->
  Json_spel_t.json_spel ->
  Json_spel_t.json_spel

set o x v add (or replace) the a field x of the object o with value v.

val get : Json_spel_t.json_spel -> string -> Json_spel_t.json_spel option

get o x gets the value of the field x of the object o.

val take : 
  Json_spel_t.json_spel ->
  string ->
  Json_spel_t.json_spel * Json_spel_t.json_spel option

  Json_spel_t.json_spel ->
  string ->
