Copy from path

[matteo-cristino]

As for the pickup statements it will be nice to have a statements like:

When I copy '' from path ''

or

When I create the copy from path ''

to copy an element with variable depth.
Moreover at the moment the pickup statement works only with dictionaries. It would be nice to have also the possibility to use it for arrays. For example suppose to have:

{
  "dict": {
    "arr": [
      {
        "mickey": "mouse",
        "donald": "duck"
      }
    ]
  }
}

it would be nice to extract the value of mickey with

When I copy 'mickey' from path 'dict.arr.1'
