When I read your first example, I immediately thought I would handle your

Hi Bruce
If I understand correctly.
$_SERVER['fname'] !?? $user->setName($_SERVER['fname']);
Will return the result of $user->setName($_SERVER['fname']) if
$_SERVER['fname'] is set or null if not set. While:
isset($_SERVER['fname']) && $user->setName($_SERVER['fname']);
Will return boolean

Hi Ken
I totally agree with Andreas especially:
One purpose of the operator should be that you don't have to repeat
> the variable. Here you do, e.g. $_SERVER['fname']
But if this operator provide some way not to repeat the variable it will
make sense. For example:
$_SERVER['fname'] !?? $user

Hi Ken,
This is definitely an interesting idea, and when described as "the
opposite of ??" the !?? syntax makes sense.
Looking at the example, though, the "negating" part becomes a bit confusing.
The verbose form reads naturally as a positive assertion - "if this is
set, do this":

Hi Ken,

Since PHP 7.0 brought forward the Null Coalescing Operator (??), writing
more succinct code for how to handle null values has been a blessing. But,
what about the inverse when you want to do something when a value is not
null? You're left with the traditional (and sometimes verbose) methods of
usin
