Shouldn't isempty(nothing) return true?

Personally, I find the “box” mental model for variables to be wholly confusing and not helpful — especially for newcomers to the language. Julia’s variables don’t really “contain” values. They’re just names. That’s it.

In that case it seems a bit odd to me that

julia> isempty(3)
false

If anything, shouldn’t isempty(nothing) be false?
