Expand description
Commands encode side-effects that will take place after a successful rule application.
A rule may require some changes to the whole tree as part of its transformations, or a change to some associated data. These changes are applied after the node changed by the rule is updated.
It may use Commands::transform to arbitrarily change entire tree after the rule has been
applied. To change the global metadata in-place, it may use Commands::mut_meta.
