No. That was actually one of the issues that perl 6 is supposed to address: the ability to add new operators. All we have today are existing operators and functions. 

sub definedor
{
  defined $_[0] ? $_[0] : $_[1]
}

I think that's as good as you're going to be able to do before perl 5.9.2.

Of course, if you want a more generic one that can take multiple inputs, sort of emulating $a // $b // $c // ..., you could do: 

sub definedor
{
  use List::Util qw(first);
  first { defined } @_
}

and use it as definedor($a, $b, $c, ...) Of course, at this point, you almost may as well use the first function directly ;-)
