Depends on your coding style. The savings could be significant for
some uses of Unbounded_String, for example. It might also be faster
to return a pointer to heap object (which is in fact region or stack
allocated) than to return the unconstrained object itself, if this
saves a few copies.
All in all, I would expect that most Ada code is far less demanding
than Java code as far as the memory allocate is concerned (assuming
that you use a compiler which can allocate unconstrained objects on
the stack).
