 Implicit isset/isempty check on short-ternary operator

I suppose a non-array-specific version would be to put it after the $.

$?variable
$?array['foo']['bar']

I wonder if you could even use : with this syntax.

$?variable:"default"
$?array['foo']['bar']:"default"

Perhaps using it in function definitions is something to consider, too,
for a callee-specified undefined-notice-silencing mechanism.

function foo($?arg) {
}

Doesn't work for the variable arguments case, though, without resorting
to something IMHO ugly/hard-to-read-and-understand like:

function foo(?) {
}

It's another idea to throw in the mix, though.

I do think the 'silent' modifier that was the original suggestion in
this thread is worth further thought. It may well allow userland
functions to be developed, which might be a benefit.

I personally, though, think a modified ternary operator like the
proposed ??: or the syntax above, is better.

Ben.
