3. It then calls `traverse` with the operation and system as arguments

handling code. If a `version` argument is supplied, then operate also
ensures that the system found satisfies it using the `version-satisfies`
method.
Note that dependencies may cause the operation to invoke other
operations on the system or its components: the new operations will be
created with the same initargs as the original one.
