makes about as much sense as the ability to lock every object, including 
those where locking is not exactly sane or useful...

to be strictly sensible, one would have to do something special for 
lockable objects as well as cloneable ones...

it is like in ActionScript, which requires a special modifier for 
dynamic objects, even though one could allow people to freely shove 
custom fields and methods into instances of any object.

it made more sense to support non-dynamic objects as well, and actually 
have these as the default case (whereas it probably would have been less 
effort implementation-wise to simply only have dynamic objects and 
optimize the non-dynamic use cases).

or such...
