I just tried to parse the file:

```julia
file_path = ~/.julia/packages/Makie/rEu75/src/Makie.jl

@info "Processing file: $file_path"
s = read(file_path, String)
@time expr2 = parsestmt(JuliaSyntax.SyntaxNode, "begin\n"*s*"\nend", filename=file_path)

```

And I am getting this error:

```julia
[ Info: Processing file: ~/.julia/packages/Makie/rEu75/src/Makie.jl
ERROR: ParseError:
# Warning @ ~/.julia/packages/Makie/rEu75/src/Makie.jl:68:35

# Warning @ /home/six/.julia/packages/Makie/rEu75/src/Makie.jl:303:8
export Vec, Vec2, Vec3, Vec4, Point, Point2, Point3, Point4
export (..)

```

Shouldn’t JuliaSyntax be able to parse all julia files? Or am I missing something?

Reproduces with all versions of JuliaSyntax.jl from v0.4.5 to v0.4.9. @c42f is this a bug?

This was fixed a couple of weeks ago: JuliaLang/JuliaSyntax.jl#477

TL;DR: Allowing parentheses in imports is bad, but the operator `..` conflicts with import paths like `..SibilingModule`. Ideally, it should be imported as `var".."`, but for now, an exception was made to allow `(..)`.

Actually this is just a warning, but warnings are set to become errors by default in `parsestmt()`. You can use `parsestmt(..., ignore_warnings=true)` to get the behavior used by `Base` Julia (currently used because there’s no way to emit parser warnings from the Julia runtime).

This particular warning was a bug and has been fixed as pointed out by @savq.
