The NameSpace type
Construction
There are two forms of data constructor:
- Source data constructors
- The data constructors mentioned in Haskell source code
- Real data constructors
- The data constructors of the representation type, which may not be the same as the source type
For example:
data T = T !(Int, Int)
The source datacon has type (Int, Int) -> T
The real datacon has type Int -> Int -> T
GHC chooses a representation based on the strictness etc.

Derive a name for the representation type constructor of a
data/newtype instance.
Deconstruction
occNameFS :: OccName -> FastStringSource
occNameString :: OccName -> StringSource
isDataSymOcc :: OccName -> BoolSource
Test if the OccName is a data constructor that starts with
a symbol (e.g. :, or [])
isSymOcc :: OccName -> BoolSource
Test if the OccName is that for any operator (whether
it is a data constructor or variable or whatever)
isValOcc :: OccName -> BoolSource
Value OccNamess are those that are either in
the variable or data constructor namespaces
parenSymOcc :: OccName -> SDoc -> SDocSource
Wrap parens around an operator
startsWithUnderscore :: OccName -> BoolSource
Haskell 98 encourages compilers to suppress warnings about unsed
names in a pattern if they start with _: this implements that test
