in reply to How to call a function on each item after a split?

Although using an array is usually a better solution, it can be done as follows:

my ($item1, $item2, $item3, $item4, $item5) = map {clean($_)} split(/\ +|/, $str);

    Actually your code assigns the return values from clean() which are either 1 or the empty string. The function uses the side effect of changing $_ but could be modified to return the trimmed string instead.

      Oops, my bad. I am so used to writing subs that return a meaningful result rather than do an in-place action-at-a-distance. MrSnrub has the right solution: just return $_ in the map.
