+During any point in the lifecyle of a command, `to_hash` can be
+called to dump out the current values. The `index` value is
+auto-incremented and the `cmd_id` is static when its passed to
+child commands. This helps with debugging and logging.
+
+```ruby
+command = CalculatePower.call(...)
+command.to_hash #=> {
+                #=>   index: 1,
+                #=>   cmd_id: "018c2b95-b764-7615-a924-cc5b910ed1e5",
+                #=>   command: "FailureCommand",
