Bug 16745 – Add template helper for creating static arrays with the size inferred

There is currently no way in the language or in Phobos to create a static array where the size is inferred. If you do something like int[5] sa = [1, 2, 3, 4, 5]; you have to explicitly give the length, and if the number of arguments ever changes, you need to explicitly change the length. There are advantages to that, but it can also be annoying to have to type the length rather than have it be inferred. And auto won't do it, because it would infer the type to be a dynamic array rather than a static one. As I understand it, at one point there was a PR for dmd which would have added a syntax such as int[$] = [1, 2, 3, 4, 5]; to implement this functionality, but it was rejected. However, it should be simple enough to create a template helper which does the same job and add it to Phobos.

How's this: https://github.com/dlang/phobos/pull/4936
