  Trying to wrap a library I am getting te following:

  In one hand have Referenced.nim:

  import Observer # Provides ObserverSet, Observer
  import DeleteHandler # Provides DeleteHandler
  
  
  type
    Referenced* {.header: "Referenced", importcpp: "Referenced", byref.} = object
      ## Base class for providing reference counted objects.
  Run

  But Observer.nim uses the type Referenced defined in Referenced.nim and it starts like:

  #import Mutex # Provides Mutex
  import Referenced # Provides Referenced
  from Referenced import Referenced
  
  Run

  If I introduce the following in Observer.nim:

  type
   Referenced* {.header: "Referenced", importcpp: "Referenced", byref.} = object
  Run

  I get a redefinition error.

  How should I hndle this situation?

  Put the types into the same module. Yeah, yeah, I know, I know.
