from [StaticArrays doc](https://juliaarrays.github.io/StaticArrays.jl/stable/pages/api/#Implementing-your-own-types-1), we can “easily” create our own `StaticArray` type… unfortunately no example is provided on the doc…
could someone be nice enough to post an example (of immutable type is good enough)? many thanks.

As the docs mention, you can look at [`MArray`](https://github.com/JuliaArrays/StaticArrays.jl/blob/98db703d0ed74b0f062f350f7de7fdcd845f4989/src/MArray.jl) — ignoring the macro, it is pretty simple.

I think it’s also good to look at [SizedArray](https://github.com/JuliaArrays/StaticArrays.jl/blob/98db703d0ed74b0f062f350f7de7fdcd845f4989/src/SizedArray.jl). I’ve made two `StaticArray` types by copying and modifying that linked file.
