And yet it is correct and your untested change unfortunately is the incorrect one. The callback you specify is not called with each element as an argument $cb->($el);, but with it as a localized default variable, as in grep() and map(): { local $_ = $el; $cb->(); }.

ok, thank you for the correction!
