Meanwhile, i had already created a patch implementing a NULL type for scripts vars. It seems rather trivial. I'll test it in some real cases.



Example:
xlog("$$var(uninit) = $var(uninit)");

$var(null) = $null;
xlog("$$var(null) = $var(null)");

$var(test) = "test";
xlog("$$var(test) = $var(test)");

$var(test) = $null;
xlog("$$var(test) = $var(test)");

$var(test) = 1234;
xlog("$$var(test) = $var(test)");

$var(test) = $null;
xlog("$$var(test) = $var(test)");


Output:
$var(uninit) = <null>
$var(null) = <null>
$var(test) = test
$var(test) = <null>
$var(test) = 1234
$var(test) = <null>
