I can see your point, but note that active bindings are not necessarily slow, 
and a special treatment may not be desirable in all use cases. For instance in 
RKWard, we use active bindings to detect, when objects are modified. To do so, 
we move *al* objects from .GlobalEnv to a hidden storage environment, and 
place corresponding active bindings in .GlobalEnv, instead. So, in our case, 
we'd clearly like for active bindings to behave just like regular objects, as 
much as possible.
