Ada requires the full definition of a private type to be
in the package spec, but it doesn't require the declaration
of "helper" functions the way C++ does. Helper functions
can be declared in the package body, without perturbing the spec.
[In C++, one can use a "friend" class to contain the helper
functions, but that is pretty obscure.]
Note that both C++ and Ada allow access/pointer types to be declared
without exposing the full details of the target type.
