Is there a place for part of this logic in Phobos?
I'm thinking perhaps array{N,Exactly} should be added to
std.array.
The idea came to me after learning about dependent types in
Idris:

There was a pull request awhile back for a small function that
creates fixed-length arrays, but I think it was only intended to
create them from dynamic arrays (such as `auto sarr = [1, 2,
3].staticArray`). Personally I think it would be nice to have a
version of `array` that creates a static array, but I don't know
how often it would be used or what the pitfalls are, if any.
