Made a package to supplant non-FFI uses of `Ref`:

> [ZeroDimensionalArrays.jl](https://github.com/JuliaArrays/ZeroDimensionalArrays.jl) is being registered, meaning it has entered the three-day-long wait period. Feel free to suggest breaking changes until the wait period is over! It’s a tiny package, implementing several similar types, each being a zero-dimensional array. The package is a response to the frequent confusion regarding Ref because of the semantic overloading, and the fact that Julia programmers often don’t expect Ref to be an abstract type. It’s meant to replace most/all non-ccall-related…
