I believe someone mentioned that it is a &quot;smarter&quot; form of
&quot;||&quot; that is due to be included in a future release of
Perl.&nbsp; In this example, if the value to the left of &quot;//&quot; is
a value, zero or empty string, then the value the &quot;//&quot; operator
returns will be the value/zero/empty string respectively.&nbsp; If the
variable is not defined (or possibly &quot;NaN&quot; or other error
values), then it will return the value on the right side of the
&quot;//&quot; operator.<br/>

I haven't seen a writeup of this new functions planned implementation
rules so this might be way off.<br/>
