Additional whitespace means *any* whitespace. Not just line ends. And
I've seen far too many codebases that use spaces around double colons
(or arrows or a lot of other things) like this:
A :: b();
Not allowing that on a language level just to avoid people shooting
their own foot while we have enough userland tools to at least make
people aware of such issues (like php_codesniffer, php-cs-fix or –
perhaps even better – phpunit) feels a bit drastic to me.
Cheers
