I am smelling an XY Problem. So here is some code that takes $text and creates an array @words containing all the words in $text. In addition, it adds a comma to each word, but my guess is, that you are not really interested in that... 

use strict;
use warnings;

my $text = <<EOTEXT;
This is a word.
Here is another sentence.
EOTEXT

my @words = $text =~ /\b(\w+)\b/g;
print "@words\n";
$_.="," for @words;
print "@words\n";

Thanks to toolic for the sample text.
