There is one technical issue which I have not seen addressed in this
Ada requires that exceptions occur more or less in place (the detailed
requirements can be found in the standard). This can limit code
C++ exceptions seem to be underspecified in this regard, so the
compiler is free to do what it will. Actually, C++ implicit exceptions
seem to be underspecified in general.
On the other hand, most Ada compilers allow implicit exceptions
(overflow, etc) to be turned off, and in this case, code can be moved
