(17:45:26) ikrabbe: Hey, I have a question about json pick adt
(17:46:29) ikrabbe: I can now read a string and parse it into a json variable. Acutally this is an array oj objects [{"x":"y"}] kind of
(17:47:37) ikrabbe: I do jv:ref JSON->JValue; (jv,nil)=json->readjson(bufio->sopen("[{\"x\":\"y\"}]");
(17:48:18) ikrabbe: afterwards I can pick j:=jv{ Array=> { X:=j.a[0]; }
(17:48:40) ikrabbe: so X is now the first element of the array (which should be an JValue->Object
(17:48:41) ikrabbe: )
(17:49:53) ikrabbe: but when I want to call, i.e. the text of this ref JValue, X.text() limbo tells me:
(17:50:09) ikrabbe: mod.b:398: cannot call 'X.text' without importing JValue from a variable
(17:50:25) ikrabbe: I absolutely don't understand what this means
(17:51:09) ikrabbe: can anyone bring me some light?
(18:05:34) ikrabbe: I think I got it finally, thx for your audience

(18:16:25) ikrabbe: hmm, is there a more direct interface to pick? I know what I get, so I'm fine if I can jv->a[0]->mem.get("name").s
(18:17:01) ikrabbe: for example to get the first element of an array of objects parsed into jv, which has a member "name" which is of value type string
