The only way to statically enforce exception contracts is to use SPARK
Ada (http://www.praxis-his.com/sparkada/). SPARK Ada does do exactly
that (among other things); it also signficantly restricts the Ada
language to a manageable subset.
So if you like exception contracts, use SPARK Ada.
If you like all the things SPARK Ada leaves out (I don't have the
current list handy; it doesn't seem to be on the web site), use
standard Ada.
