Right. And also :

array(1,2,3)
    |> array_map(function($x) { return $x * 2; })
    |> $intermediate_var
    |> array_sum()
    |> $ret;

Talking about arrays, I am also thinking of a '[]>' operator (name may 
vary). This would take an array as input, and output another array, 
where every value would have been run through the function. The keys 
would be preserved. Example :

array('a','b','key' => 'c') []> ord(); // produces [ 97, 98, 'key' => 99 ]
