Shure. That's one more reason for variable_exis
oooh,
here is easy sollution for global vars :
However there is no $LOCALS in the local scope.

Ok, but it still doesn't change the fact that null is not a value :) The
fact we couldn't

Yes, pretending that it is currently consistent is the problem I think.
By introducing the new function we solve the inconsistency. True there
are ways around this, such as get_defined_vars(). Interestingly, yet
another inconsistency is that get_defined_vars() also returns a variable
with a null va
Actually they are not the same, as this code illistrates:
$foo = array( 1, 2, 3, 4, 5 );
unset( $foo[1] );
foreach( $foo as $key => $value )
{
echo $foo.' -> '.$value."\n";
}
Output:
0 -> 1
2 -> 3
3 -> 4
4 -> 5
in contrast to:
$foo = array( 1, 2, 3, 4, 5 );
$foo[2] = null;
foreach( $foo

You should use var_dump instead of print_r.

Oh, you meant the first output, nevermind. I /know/ unset() and setting
something null is not the same - as probably everyone on this list.

The attached patch changes dl() so that, instead of outright refusing to
