How do I make an unbounded interval?

[fonsp]

From the docs, I can't tell how to construct an unbounded interval, except for constructing the object manually (which took me a long time to figure out):

julia> one_to_three = 1 .. 3 # nice!
Interval{Int64, Closed, Closed}(1, 3)

julia> one_and_up = Interval{Float64,Closed,Unbounded}(1,nothing)
Interval{Float64, Closed, Unbounded}(1.0, nothing)

julia> 7 ∈ one_and_up
true

Is there an easier way?

Just 1..nothing?

julia> 1..nothing
Interval{Int64, Closed, Unbounded}(1, nothing)

julia> 1.0..nothing
Interval{Float64, Closed, Unbounded}(1.0, nothing)

julia> Interval{Float64,Closed,Unbounded}(1,nothing)
Interval{Float64, Closed, Unbounded}(1.0, nothing)

I'm not sure the following behavior of nothing..nothing is not unexpected, btw.

julia> nothing..nothing
Interval{Nothing, Unbounded, Unbounded}(nothing, nothing)

julia> 3 in nothing..nothing
true

julia> 3+im in nothing..nothing
true

julia> "foo" in nothing..nothing
true

julia> Any in nothing..nothing
true
