--| @SUMMARY This package records the analysis on with clauses to determine
--| thier usage. Each withed unit is numbered 1..N. With clauses are marked
--| as used when a reference points at something in that package. After
--| all references are marked, each with clause can be interrogated
--| to determine its status.
