In the sorted case example, you are right. But having the correct code as in the example makes a change from 0 to -1 or 999 as default a very easy edit, which is not to say when using ||.

   The same goes if one were dealing with char data and used $foo || ''

Why do you want to change a perfectly valid string "0" to the empty string "". I seldom want such a change for defaults.
