I must be extraordinarily dense today, because I fail utterly to comprehend
what you are trying to say.  Ada already provides you with access to the
exception name, without parsing text, viz.

  begin
    call_some_procedure_that_might_barf(params);
  exception
    when constraint_error => handle_constraint_error(params);
    when program_error => handle_program_error(params);
    when others => raise;
  end;

Would you please clarify?
