It might depend on what you did in C++ before converting. ;-)
Since most of the code does not need pointers anyway, the frequent
idiom is to pass objects by reference (likely to the base class),
something like:

void foo(const SomeClass & object);

I don't see how moving this to Ada can lead one to use pointers -
personally, I find "in Some_Type'Class" to be very natural. No
pointers needed.

I think that in the above context what is *really* dangerous and
difficult to clean up is the C background, not C++. Unfortunately the
former one prevails.
