That ought to be "False". But that also doesn't work, as visual.scene is the 
object that complains about re-initialised, and that one is a module level 
variable, so it can only be initialised once per running Python process.

Iterating over the objects and setting their visibility to False should (A) 
just hide them, but not delete them, and (B) still leave the current scene's 
instance in the state it's in. So that's not helpful, either.

I did help myself by checking whether visible.scene.title has been changed, 
and if so then to hide all objects and not re-initialise the scene. But that's 
more of a dirty hack, rather than a real solution. It just targets this *one* 
case, and cannot be generally used for other modules using visual as it would 
be expectable from Python code.
