I saw this issue in Julia 2.0 milestone. [https://github.com/JuliaLang/julia/issues/39235](https://github.com/JuliaLang/julia/issues/39235)

I was wondering if using will be deprecated in favor of import in Julia 2.0. If that is the case, I will stop using the using right now.

You shouldn’t stop using `using`, because you will lose all exports. The proposal does not negate export semantic, so while it is not implemented `using` is needed, because it has a different meaning compared to `import`.

Even if that proposal would be considered for 2.0, that is still very far in the future, so there’s no need change your habits now.

Still, I personally like it better to explicitly say what I use already, but you can do that with `using A: b` anyway. It’s a semantic distinction.

I understand that but the possibility of deprecating using still sounds scary to users like me.

One thing to note is that we almost certainly will make upgrading to 2.0 as painless as possible. It seems likely that we’ll have a script that can automatically do the changes from 1.x to 2.0. Also, I wouldn’t be surprised if we end up not changing this. While it obviously would be better to have 1 keyword, breaking changes that don’t solve problems are often not worth fixing.

It depends on the definition of “problem”. If getting rid of `using` makes the semantics of importing code simpler, then I think it would be worth it. After all this time I still sometimes get confused about the difference between the two and the reasoning behind the design.

Version 2.0 is likely to contain _several_ breaking changes. How will you handle that?

Are you sure you’re not overreacting? It seems like upgrading will be difficult if you’re that change-averse.
