SortedRange and new docs for std.container

[Andrej Mitrovic]

I don't want to hijack the topic, but can I ask a question?

In the Phobos docs I often see this kind of code:

assert(equal(radial(a), [ 3, 4, 2, 5, 1 ][]));

What is the purpose of the extra square brackets after the array
literal? Because the code works both with and without them.
