So you just want a convenient and readable way and you realise yourself, 
that it is really simple to implement. So: Why don't you just implement 
it yourself?


function array_delete($array, $value) {
   // Your code here
}


What I don't understand is, why should every function goes directly into 
the core, if you can achieve exactly the same without core changes?
