+/**
+ * The purpose of TransitName is to allow a library to 'move' a name
+ * call to a more appropriate place.
+ * For example, a library factory function may create a module and return
+ * the io. The only user-exposed field is that given IO, which can't use
+ * any name supplied by the user. This can add a hook so that the supplied
+ * name then names the Module.
+ * See Queue companion object for working example
