Yes, and as the person who came up with that, I was well aware of the irony. It was originally this:

  declare(strict_typehints=TRUE);

However, I changed it to the form that you see there because it was shorter. I felt that in the grand scheme of things it's not very important: declare() isn't a function, it's a language construct, and saving 5 chars from something that'll be typed very frequently is probably worth it.
