+-- restrictions that applies to the current partition. The information
+-- comes both from explicit restriction pragmas present, and also from
+-- compile time checking.
+
+-- The package simply contains an instantiation of System.Rident, but
+-- with names discarded, so that we do not have image tables for the
+-- large restriction enumeration types at run time.
