To be more exact, [3,4,2,5,1] use to create a static array, int[5u], but what was required was a dynamic array, int[], by adding the ending [] you are taking a 'slice' of the entire array, which is of type int[]. adding the [] to the end still does the same thing, but now array literals are dynamic arrays. You can use literals to create static arrays by giving the type you want.

The default was changed because Phobos was littered with [...][] in all the tests... Andrei must have gotten annoyed. :)
