As part of my current contract, I've got to deal with a text field that contains email addresses. These addresses should be seperated by whitespace or commas or combinations thereof (It's going to be used by salespeople, so simply telling them to follow a specific format is out of the question). Here's some example input: 
  foo@foo.com bar@bar.com,   foo@foobar.com 
bar@foo.com , bar@foobar.com

[download]
etc. I struggled with a regex for an hour or so, and came up with this: 
 my $addresses = $form_fields->{addresses};
 my @addresses = map( $_ =~/(\S+)/, split /\b(?:\s+|(?:\s*,\s*))\b/, $
+addresses);

[download]
where $addresses contains the data POST'ed from the textarea. I feel like this should be possible without the map, but I couldn't make it work (any regex I came up with would choke on leading / trailing whitespace). Anyone care to turn this into one regex?
