Why? What part of that "nature" requires it?

From the point of view of object model and execution model, C++ and
Ada are very similar. Compilation and deployment strategies are more
or less equivalent.

To be honest I'm not sure why you came up with such an idea.
Formally, the C++ standard places no restrictions on how this should
be done.

Don't worry, C and C++ are a frequent target of criticism here, so we
might as well discuss some details from time to time. ;-)

Because the code-expansion model is easier to implement and that's
what most (all?) compiler vendors chosen to do.

But, for the sake of exercise, think about a C++ *interpreter*.
