This should be defined in Base as well, right?

We should add this replacement to Compat.

I was going to, but it's weird because IteratorSize is defined in 0.6 too.

Fredrik is adding it in Compat as Compat.IteratorSize, so we could use that if this PR is merged after his is merged and tagged.

Why @static here and not in other places? I'm not sure whether it's needed.

It's not necessary at the top level (though I think you can use it to get around deprecations from the parser) but it doesn't hurt.

@nalimilan, are we maybe missing a promote_rule in the Base definitions? I'm seeing

julia> promote_type(Union{Nothing, Missing, Int}, Float64)
Union{Missing, Float64}

on 0.7 (as of today).

That's JuliaLang/julia#24653 (comment). See also JuliaLang/julia#25240.

But why comment this out? Isn't it still broken?

It's not broken on 0.6 though

How did tests pass then? :-/

If it's

@test promote_type(Union{Nothing, Missing, Int}, Float64) == Any

it passes on 0.6, fails on 0.7.

if it's

@test_broken promote_type(Union{Nothing, Missing, Int}, Float64) == Any

it passes 0.7, but fails 0.6 (because it's NOT broken on 0.6, "unexpected pass")

so to pass on 0.6 and 0.7, I just comment it out 😄

OK. Why not make it conditional on the version then?
