I have an array of strings and I want to replace it with a new word, s
+o I do this:

$line='i got a dog and a bear.';
@a=('dog','bear','camel');
$a=join('|',@a);
$line=~s/\b($a)\b/beast/g;
say $line;

Simply works, but the problem is that @a is not hard-coded, but instea
+d inputted by the user.  The elements in @a will contain special char
+acters like | or . etc.  How do I make this regex work with the antic
+ipation of those characters?
