Create array initializers and allocate arrays without curly braces in Julia.
The initializer instances can be passed as the first argument of an AbstractArray
constructor to initialize the array.
If the initializer is typed, the element type of the AbstractArray
constructor is optional.
Compatible with OffsetArrays
and other subtypes of Julia arrays that implement Base.fill!
