post_key_check(key)

private

After we see a key, we must look ahead to determine our next action. Cases:

  [] follows the key. Then the value must be an array.
  = follows the key. (A value comes next)
  & or the end of string follows the key. Then the key is a flag.
  otherwise, a hash follows the key.

      def post_key_check(key)
        if scan(/\[\]/) # a[b][] indicates that b is an array
          container(key, Array)
          nil
        elsif check(/\[[^\]]/) # a[b] indicates that a is a hash
          container(key, Hash)
          nil
        else # End of key? We do nothing.
          key
        end
      end
