Description:
------------
if there is a `declare(strict_types=1);` string to number casting should be avoided, for example:

var_dump('20' < '3');// is false

Pros/Cons:

+ it will be faster (no if string is a number check, no casting)
+ it will be common (with strings, compat with other langs like JS, Python)
+ it will be more error prone (because it's common)

- some old code which rely on this feature will break (does it exist?)









Test script:
---------------
var_dump('20' < '3');

Expected result:
----------------
true

Actual result:
--------------
false
