The look function reads global variables. It is not Functional!
Let's try it:
  ==> (you are in the living-room of a wizards house - 
       there is a wizard snoring loudly on the couch - 
       there is a door going west from here - 
       there is a stairway going upstairs from here - 
       you see a whiskey-bottle on the floor - 
       you see a bucket on the floor - )
Pretty cool!
