+\section[PrelNames]{Definitions of prelude modules and names}
-The strings identify built-in prelude modules. They are
-defined here so as to avod
-[oh dear, looks like the recursive module monster caught up with
- and gobbled whoever was writing the above :-) -- SOF ]
+Nota Bene: all Names defined in here should come from the base package
+
+* ModuleNames for prelude modules,
+ e.g. pREL_BASE_Name :: ModuleName
+
+* Modules for prelude modules
+ e.g. pREL_Base :: Module
+
+* Uniques for Ids, DataCons, TyCons and Classes that the compiler
+ "knows about" in some way
+ e.g. intTyConKey :: Unique
+ minusClassOpKey :: Unique
+
+* Names for Ids, DataCons, TyCons and Classes that the compiler
+ "knows about" in some way
+ e.g. intTyConName :: Name
+ minusName :: Name
+ One of these Names contains
+ (a) the module and occurrence name of the thing
+ (b) its Unique
+ The may way the compiler "knows about" one of these things is
+ where the type checker or desugarer needs to look it up. For
+ example, when desugaring list comprehensions the desugarer
+ needs to conjure up 'foldr'. It does this by looking up
+ foldrName in the environment.
+
+* RdrNames for Ids, DataCons etc that the compiler may emit into
+ generated code (e.g. for deriving). It's not necessary to know
+ the uniques for these guys, only their names
+
