## #9275 — Jason Garber — 2004-04-16T20:02:42+00:00

I completely agree with the EXACT way Marcus has proposed this operator.

The key is that the first argument must be a Variable, because it is tested 
to see if it ISSET(), not if it's null.  That is why you can't have any 
expression for the first argument - it would be like calling isset('foo'), 
which does not make any sense.

I think that this internal function addresses the need exactly, and that 
the correct solution has been arrived at.

Thanks Marcus!

Sincerely,
Jason Garber
