Is there a way to implicitly convert two variables with the same _intrinsic type_ but coming from different modules? see below for example

```julia
LoadError: MethodError: no method matching synthetise_schedule(::Array{Main.Scheduler.Loader.Entities.Agent,1}, ::Array{<http://Main.Scheduler.Loader.Entities.Space|Main.Scheduler.Loader.Entities.Space>,1}, ::Dict{String,Array{String,1}})
Closest candidates are:
synthetise_schedule(::Array{Main.Scheduler.Entities.Agent,1}, ::Array{<http://Main.Scheduler.Entities.Space|Main.Scheduler.Entities.Space>,1}, ::Dict{String,Array{String,1}}) 

```

For instance,  
`<http://Main.Scheduler.Loader.Entities.Space|Main.Scheduler.Loader.Entities.Space>` and `<http://Main.Scheduler.Entities.Space|Main.Scheduler.Entities.Space>` refer to the same element but for some reason they are not considered the same type.  
I don’t export types in any of my modules and sub-modules, but I have the following `using` statements at the top of my `Scheduler` module

```julia
using .Loader: load_data, read_config
using .Entities: Agent, Space, Event

```

You should be importing the shared type from one module, and that module, call it M, should have `export Typename` (for your Typename) near the top of the file (after the line beginning `module`). Other modules that want to use that type should have a line `using M: Typename` near the top of the file (after any export lines).  
The example below is as typed into the REPL (hence the dots).

```julia
module A
  export MyType

  struct MyType
    x::Int
  end

  # etc
end

module B
   using ..A: MyType
   # etc
end

module C
  using ..A: MyType
  # etc
end

# now they are all the same
using .A: MyType # ok
using .B: MyType # ok
using .C: MyType # ok

```
