Description:
------------
In PHP 7, "[] + 1;" seems to cause compile-time Fatal Error.

The important thing is that the issue occurrs on "array literal + non-array literal" expressions. If either opereand gets turned to be a variable, PHP 7 behaves as same as PHP 5.

Test script:
---------------
<?php
exit;
[] + 1;


Expected result:
----------------
No outputs.

Actual result:
--------------
PHP Fatal error:  Unsupported operand types in - on line 3

In PHP 5, direct call for __clone() causes E_COMPILE_ERROR. So we should change Compilte-time E_ERROR into E_COMPILE_ERROR or Runtime E_ERROR.

I'm sorry, could you please be more precise about what the issue is here. Yes, it changed to a compile-time error... but what of it? Why is this a problem for you?

Although I have no problem with this, it seems to be an unexpected change. If developers have explicitly changed the feature, there are nothing to say. Sorry and appreciate for your response.
