What is the story with `include` in embedded Julia on 0.7+? If, for example, you add

```julia
        checked_eval_string("include(\"LocalModule.jl\")");

```

in the embedding example (`test/embedding/embedding.c`), the result is

```julia
UndefVarError: include not defined

```

To be able to include something you need to do `Base.include(Main, filename)` instead or start out with an eval of `include(x) = Base.include(Main, x)`. Is this a feature or a bug? If it’s intentional I think it needs some kind of mention in the documentation.

I also would love an explanation for this. I’ve just spent all morning banging my head against working out that a failure to include some code was causing all my errors. Your work around has at least got me progressing further.

As an aside I’d love to see your definition of `checked_eval_string` - I’ve got a really rough one myself that could do with a clean up.

I was referring to `checked_eval_string` in the embedding example in Julia’s source code: [https://github.com/JuliaLang/julia/blob/master/test/embedding/embedding.c#L17-L31](https://github.com/JuliaLang/julia/blob/master/test/embedding/embedding.c#L17-L31)

Depending on how you do your embedding you might find things of interest in some of these issues and a PR:

Those are great references, and should help,

Thanks.
