Hi Internals,
I would like to suggest you a new feature (for PHP5.4 or maybe next).
The idea is to implement the \Countable interface into closures to
easily count the arguments number. I know that it is already possible
with reflection [1] but it could be a comfortable trick I think.
Subsidiary questions: do we include optional arguments in our calculation?
Here is a trivial example:
class Closure implements \Countable { … }
$f = function ( $x, $y, $z ) { … };
var_dump(count($f));
// int(3)
Javascript already implements this [2]:
var f = function ( x, y, z ) { … };
console.log(f.length);
Thoughts?
Best regards.
