I usually think about decorator as a tag or marker instead of function 
calling. When I put the property decorator, I'll be thinking about 
attaching a property tag to the function so the interpreter would handle 
the function as if it is a property. This way, I don't think of it as 
implicit function calling but as an explicit tag (how the tag system 
works is a detail I need not to care).
