Can one add elements of array to an array?
E.g. given the document
{ "a" : { "b" : [ "red", "green" ] } }
If I want to add two values to an existing array, I can use
[
{ "op": "add", "path": "/a/b/-", "value": "blue" },
{ "op": "add", "path": "/a/b/-", "value": "yellow" }
]
(I found in the examples how an array index is specified in the path, not in a separate "index" member;
I guess my comments there should be directed at draft-ietf-appsawg-json-pointer-06 )
However, for appending to arrays, I would like to use
[ { "op": "add", "path": "/a/b/-", "value": [ "blue", "yellow" ] } ]
Reading the spec literally, I expect that this will yield
{ "a" : { "b" : [ "red", "green", [ "blue", "yellow" ] ] } }
instead of the desired
{ "a" : { "b" : [ "red", "green", "blue", "yellow" ] } }
I suggest the semantics of this case should be explicit, to avoid unexpected surprises.
