 * @brief Convenient alias to axl_list_lookup to implement axlList foreach operation.
 *
 * Because \ref axl_list_lookup can be used to implement a foreach
 * function (making \ref axlLookupFunc to always return axl_false)
 * this alias exists to write code that is pretending doing a lookup
 * (so developer can read it easily). That is, the alias just exists
 * to allow writing \ref axl_list_foreach instead of \ref
 * axl_list_lookup when a foreach is implemented (not a lookup).
 *
 * @param list The list where the foreach operation will take place.
 *
 * @param func The handler that will be called for each item found in the list.
 *
 * @param data Optional user pointer that will be passed to the
 * foreach function along with the item list data.
