False positive: Missing reference: Base

[jakobnissen]

To reproduce this:

• Julia version 1.9.1 or 1.9.0 (it probably also works with earlier versions but I did not test)
• Latest version of Julia for VSCode (as of 2023-06-08)
• Create a new package Foo with the following content in Foo/src/Foo.jl:

module Foo

baremodule Flags
using Base: @enum
@enum Flag flag
end

end

• Add StructTypes v 1.10.0 to the Project.toml. The error does not occur if StructTypes is not in the Project.

The following lint is displayed (see attached file)

However, it works fine, as Base is always importable in baremodules:

julia> using Foo

julia> Foo.Flags.flag
flag::Flag = 0
