This paragraph starts with "When using the const keyword ...", and the
preceding paragraph states, "the const keyword has restrictions as outlined
in the next paragraph."
Your change does not make sense in this context, the old description (being
able to do "const FOO = array('a', 'b', 'c');" as of PHP 5.6.0) was correct.

It would be good to mention the PHP 7.0.0 change (to allow "define('FOO',
array('a', 'b', 'c'));") on this page, but that was not the correct place
to do it.
