I think it is just possible that Paul may have heard
of ASIS before :-) :-) :-)

A peculiar statement, since it represents such little
awareness of what actually goes on the field. In fact we
see many large users who are migrating large Ada 83 applications to
Ada 95, and I would guess exactly the
opposite that automated code transformations (I find the
term refactoring pompous :-) for, e.g. replacing certain
stylized uses of tasks in Ada 83 with protected types to
be potentially one of the most useful forms of this
technology. Certainly we have seen people write ASIS tools
to assist in transformations of this type.
