Hi internals, I Would like to present a possible new "::func resolution" for your consideration.
In first place, PHP now support "::class" in this way: use My\I18N; $mapped_array = array_map([I18N::class, 'translate'], $array); It avoid add Full I18N namespace in callback. However with functions is different: use function \My\I18N\i18n_translate; $mapped_array = array_map('\My\I18N\i18n_translate', $array); What is the useful here of importing the function?. My proposal is ":func" in order to avoid full namespace in callback of functions. E.g: use function \My\I18N\i18n_translate; $mapped_array = array_map(i18n_translate::func, $array); "<string>::func" should validate if a function with `<string>` is imported. In this case, "<string>::func" is replaced with FQN of this function, otherwise with only "<string>" What is your opinion ? Do you see it useful ? Thanks and I'm sorry for my English( I'm a Spanish ). Regards
