indexed function:

Map a list into a new list where each element in the new list is an object with two elements:

• index with the index of the element in the list
• value with the element in the original list Can be used later for filters or map based on index. If the first argument is not a list will return nothing.

Examples:

• running: (indexed [false, null, 10, {}]) will give: [{"value": false, "index": 0}, {"value": null, "index": 1}, {"value": 10, "index": 2}, {"value": {}, "index": 3}]

• running: (indexed {}) will return nothing
