Good bindings are hard, for any language. Most bindings are not good for 
that reason.

I would guess that you are off by an order of magnitude, but of course it 
would depend on precisely what you are doing and how the existing code 
works.

Remember that the best way to do something in C++ is not necessarily the 
best way to do something in Ada (and vice-versa). For instance, C++ programs 
use altogether too many pointers (references) for good Ada. To make a really 
great Ada binding, you need to design it in Ada -- writing C-in-Ada does not 
buy much.
