Weird Module Error

New to Julia

I just developed a Package for Julia https://github.com/Elzair/merchantjl. First I just created one module in the main file and just include()d all code under it.

Merchant.jl

module Merchant
include("worldinfo.jl")
# ...
export World, seekAllPassengers, # ...
end

@v1.8) pkg> activate .
  Activating project at `~/Development/misc/julia/Merchant`

julia> using Merchant: seekAllPassengers, World

julia> seekAllPassengers(2, 2, World("A434934-F"), World("A560565-8"), 2)
Output...

It works, but I would like to split the code into multiple modules, so I created a “modules” branch for that. However, to use World (defined in module WorldInfo), I now need to import the main module as well and specify a full path (even though I import and re-export in my main module).

Merchant.jl

module Merchant

include("worldinfo.jl")
include("passenger.jl")
# ...

using .WorldInfo: World
using .Passenger: seekAllPassengers
# ...
export World,  seekAllPassengers, # ...
end

worldinfo.jl

module WorldInfo
export World, #...
struct World
# ...
end
end

passenger.jl

module Passenger
include("worldinfo.jl")
using .WorldInfo: World
export seekAllPassengers
function seekAllPassengers(..., source::World, ...)
# ...
end
end

@v1.8) pkg> activate .
  Activating project at `~/Development/misc/julia/Merchant`

julia> using Merchant: seekAllPassengers, World

julia> import Merchant

julia> seekAllPassengers(2, 2, Merchant.Passenger.WorldInfo.World("A434934-F"), Merchant.Passenger.WorldInfo.World("A560565-8"), 2)
Output...

The problem is I have three main functions in three different modules, and they all use World.

julia> seekAllFreight(2, Merchant.Freight.WorldInfo.World("A434934-F"), Merchant.Freight.WorldInfo.World("A560565-8"), 2)
Output

Does anyone know how to fix this?

I found Defining Multiple Modules in a Package, and it suggested that my first approach was the correct one, so I will stick with that.
