in reply to Ways to control a map() operation
You can exit map() with a return, like this: sub{ map { print ; return if 5 >= $_ ; $_ } @arr; }->();
but in doing so, now you can no longer store the map-derived values to a named array, you will have to push them:
# This is no good, values are not stored in @early: sub{ @early = map { print ; return if 5 >= $_ ; $_ } 3..9; }->();
# This is how to store values into @early : sub{ map { print ; return if $_ == 5 ; push @early, $_ } 3..9; }->(); Here is the full snipplet:
my @arr = 3..9 ; our @early; sub{ map { print ; return if $_ == 5 ; push @early, $_ } @arr; }->(); print "@early";
