What is the difference between a zero-dimensional array holding the value x, which you construct using fill(x), and a Ref(x)? In both cases you would access the underlying data via [], which can be set or read. And it seems that both store a pointer to the actual data.

One is an array — which means that it supports a bit more arithmetic and such like: julia> fill(1) + fill(2) 3 Ref is about as barebones of a 0-dimensional container as you can get. But just like all 0-dimensional containers, it’ll work nicely with broadcast.

Ref vs zero-dimensional arrays?
