Equality of empty ranges

Internals & Design
1

In order to be equal, ranges need to have the same first element, last element, and step, even if they are empty. In my opinion, this is unintuitive:

julia> 2:1 == 1:0
false

It also breaks the transitivity of ==:

julia> 2:1 == Int[] == 1:0
true

Is this behavior intentional? (And if it is, what is the intention?)

That does seem like a bit of a problem; could you open a GitHub issue?
