[julia-users] difference between None, Nothing and nothing

[Michele Zaffalon]

I could not see anything in the docs and I could only understand the
"nothing" keyword:

julia> function f()
       return
       end
f (generic function with 1 method)

julia> f()==nothing
true

julia> nothing==Nothing
false

julia> nothing==None
false

julia> Nothing==None
false

julia> Nothing==Nothing
true

What is the meaning of Nothing and None?

Thank you,
michele
