Note that it is not possible to know which AST is chosen by the default merge function. That's why the default merge function should be only used when the two AST are the same. But it will work if the ambiguity is caused by the same rule having two different actions, i.e. if you added a rule that already existed but with an associated action that is different, then the latest action will be used. (and no merge function is used in this case). The name of the default merge function "keep_older" is misleading and I should change it for "keep_one" instead.
