ref function does not resolve recursively eval: when it is referencing an object (?)

Suppose we have

{
  "obj": {
    "c": "eval:string:$(ref $(cur).a)",
    "a": "Howdy"
 }
  "key": "eval:object:$(ref $(cur).obj)"
}

In this situation, since .key.c doesn't appear in the list of attributes to be templated initially created, the node will have a value eval:string:$(..., not Howdy.

Probably we should repeat perform_templating function until all the templating keywords (eval: and template:) go away.

Example:

{
  "objectNode": {
    "hello": "eval:string:$(ref .stringNode)"
  },
  "refObjectNode": "eval:object:$(ref .objectNode)",
  "stringNode": "world"
}

This renders to

{
  "objectNode": {
    "hello": "world"
  },
  "refObjectNode": {
    "hello": "eval:string:$(ref .stringNode)"
  },
  "stringNode": "world"
}

While we want to make it converted to

{
  "objectNode": {
    "hello": "world"
  },
  "refObjectNode": {
    "hello": "world"
  },
  "stringNode": "world"
}
