I still think that having a more "functional" code block wins over consistency. I see people copy and paste from the docs all the time - and even our missing `<?php` in PHP code blocks sometimes causes problems. So would still vote for the `// ...` in multi-line arrays, even if we have `array('foo', 'bar', ...);` for single-line arrays.

But I don't feel too strongly either way in specific cases - just generally, the more we can make code blocks work when you copy-and-paste, the better :)
