It was already possible to declare arrays, but the new, shorter array
syntax still brings a smile to my face :) Few new language features
actually add things that weren't possible before.

I was speaking of user-space libraries/code. I'm not expecting all of
PHP core to change. I believe making the changes to the parser to
facilitating this approach in user-space code would be worth the
effort, and user-space libraries could normalize the error approach as
they see fit.
