What we need is 'closure only callback'.
If we have it, then we don't have to worry about string callback functions.
if (in_array(function($elem) {return is_numeric(strstr($elem));}, $array))
{ ... }
Why don't we have 'closure' as signature? It can do more than calling
a function.
bool in_array(closure $callback, array $ary);
Cons would be we cannot search closures in $ary.
Is there any use of searching closure?
