The D standard library is built on GC, is that a negative or positive?

Shouldn't the actual implementation of the exception handling be 
hidden as much as possible towards the programmer, at least on 
the receiving end. Exposing it too much might lead to that any 
change in the implementation might not be possible in the future.

When you catch an exception, is it then important for the 
programmer to know how the exception was thrown or can this be 
done auto magically under the hood?
