For a developer as me, this is probably the best solution indeed. I do 
manipulate lots of handles in my applications and do not really want to 
take care of which basic type they are. I'd be more than happy to 
re-engineer my applications diversifying handle types which means to get 
rid of all this ambiguity when addressing OS objects. My problem then 
would be to use the right handle type where needed
