When you use the double quotes: $arg looks like foo (bar)
But when you use single quotes, there is no expansion just what you
enter is what you get, so the $arg looks like foo \(bar\)
Obviously the second is not what you want. SO using single quotes,
you set $arg like 'foo (bar)'
Wags ;)

What is the difference between:
$arg = "foo \(bar\)";
and
$arg = 'foo \(bar\)';
when using like:
s/$arg/bleah/;
One works, one doesn't.
Why?
