Re: creating operands

As you cannot create definedor operand and don't want to wait for Perl 5.10, emulate it (differs from previos variants, as assigns $self->error to $foo, what you maybe (???) want to do):

$foo = defined($bar->id) ? $bar->id : $self->error('blah blah');

That's not equivalent. If you wanted to use the ternary operator, `defined($foo = $bar->id) or $self->error('blah blah');` would be equivalent to `defined($foo = $bar->id) ? undef : $self->error('blah blah');` `$foo = defined($bar->id) \|\| $self->error('blah blah');` would be equivalent to `$foo = defined($bar->id) ? $bar->id : $self->error('blah blah');` but that's not relevant here.
