So, this line:

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

makes each item either "1" or "" based on (I guess) whether there's empty space between the "item" string and the pipe symbol.

However, this line:

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

...does EXACTLY what I want in only one line, no matter how many items I have. Many thanks! Question, though: I don't exactly see what is going on with the added $_;. It's not returning a value, since this is not a subroutine. It's not changing the value of $_;. I guess what it does is it tells map to return $_ as opposed to the return value of the previous statement. Is that accurate?
