 An {{{OccName}}} is more-or-less just a string, like "foo" or "Tree", giving the (unqualified) name of an entity. 
 Well, not quite just a string, because in Haskell a name like "C" could mean a type constructor or data constructor, depending on context. So GHC defines a type OccName (defined in basicTypes/OccName.lhs) that is a pair of a {{{FastString}}} and a {{{NameSpace}}} indicating which name space the name is drawn from. The data type is defined (abstractly) in [[GhcFile(compiler/basicTypes/OccName.lhs)]]:
-{{{
-data OccName = OccName NameSpace FastString
+{{
+data OccName = OccName 
+    { occNameSpace  :: !NameSpace
+    , occNameFS     :: !FastString
+    }
 }}}
-The {{{EncodedFS}}} is a synonym for {{{FastString}}} indicating that the string is Z-encoded. (Details in [[GhcFile(compiler/basicTypes/OccName.lhs)]].) Z-encoding encodes funny characters like '%' and '$' into alphabetic characters, like "zp" and "zd", so that they can be used in object-file symbol tables without confusing linkers and suchlike. 
+{{{FastString}}} is a packed string implementation of strings. 
 
 The name spaces are:
