Would that function return True or False at --B in the code below ? And if it
is called from a subprogram that is called form --A ? I think the concept of
"being in an exception handler" is just not so easy to define well.

begin
   ...  --A
exception
   when e =>
      begin
         ...  --B
      exception
         when f =>
            ...
      end;
end;
