Read array length

[elliotpryde]

I'd like to be able to parse the following

arr:
- name: first
  version: 1.0
- name: second
  version: 2.0

into a structure that preserves the relationships between array element properties.

For example the following snippet preserves the relationship via the array index, however, we can't loop through indexes unless we know the array length.

arr[0].name
arr[0].version

Having functionality similar to jq's length function would allow us to write more filtering logic based on what yq returns.
