-- the package where the pragma appears. The check is inserted according
-- to the following precedence rules:
-- 1) If the package has a body with a statement sequence, the check is
-- inserted at the end of the statments.
-- 2) If the package has a body, the check is inserted at the end of the
-- body declarations.
-- 3) The check is inserted at the end of the visible declarations.
