Support Julia pre-v1.11?

[nsajko]

I think we could easily support Julia versions before v1.11 something like this: instead of defining struct FixedSizeArray directly at the top level, we could use @static if:

@static if VERSION < v"1.11-"
    struct FixedSizeArray{T,N} <: DenseArray{T,N}
        mem::Vector{T}
        size::NTuple{N,Int}
    end
    parent_type(::Type{<:FixedSizeArray{T}}) where {T} = Vector{T}
else
    struct FixedSizeArray{T,N} <: DenseArray{T,N}
        mem::Memory{T}
        size::NTuple{N,Int}
    end
    parent_type(::Type{<:FixedSizeArray{T}}) where {T} = Memory{T}
end

A downside is that this could complicate #33.

Given that Julia v1.11 seems to be getting released soon anyway, I'm not sure that it makes sense to do this, though.

That's a neat trick, but I'm not sure it's worth it. I think it's better to stick to Memory & Co. only, and forget about compatibility with older versions of Julia.

Actually, @static is not even necessary. A cleaner design than proposed above would simply introduce a single additional type parameter for the underlying storage type. This could fix this issue and #33 at the same time quite elegantly.

@longemen3000 could you list some motivating points for doing this?

[longemen3000]

I want to use this library in one of my projects, but we have compatibility with Julia 1.6 (changing the minimum compat to 1.10 as soon as 1.11 is released), so adding this dependency would not be possible on those systems.

[nsajko]

Given that Julia v1.10 will become LTS (I think I read that somewhere?), perhaps we should support it in some manner.

On the other hand, perhaps our users could use the package extension mechanism, available in Julia v1.10, to work around the incompatibility themselves?

that would work on direct users of FixedArrays, but not indirect users via indirect dependencies i think?
