\section[PrelNames]{Definitions of prelude modules and names}


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


Note [Known-key names]
~~~~~~~~~~~~~~~~~~~~~~

It is *very* important that the compiler gives wired-in things and things with "known-key" names
the correct Uniques wherever they occur. We have to be careful about this in exactly two places:

  1. When we parse some source code, renaming the AST better yield an AST whose Names have the
     correct uniques

  2. When we read an interface file, the read-in gubbins better have the right uniques

This is accomplished through a combination of mechanisms:

  1. When parsing source code, the RdrName-decorated AST has some RdrNames which are Exact. These are
     wired-in RdrNames where the we could directly tell from the parsed syntax what Name to use. For
     example, when we parse a [] in a type we can just insert an Exact RdrName Name with the listTyConKey.

     Currently, I believe this is just an optimisation: it would be equally valid to just output Orig
     RdrNames that correctly record the module etc we expect the final Name to come from. However,
     were we to eliminate isTupleOcc_maybe it would become essential (see point 3).

  2. The knownKeyNames (which consist of the basicKnownKeyNames from the module, and those names reachable
     via the wired-in stuff from TysWiredIn) are used to initialise the "original name cache" in IfaceEnv.
     This initialization ensures that when the type checker or renamer (both of which use IfaceEnv) look up
     an original name (i.e. a pair of a Module and an OccName) for a known-key name they get the correct Unique.

     This is the most important mechanism for ensuring that known-key stuff gets the right Unique, and is why
     it is so important to place your known-key names in the appropriate lists.

  3. For "infinite families" of known-key names (i.e. tuples, Any tycons and implicit parameter TyCons), we
     have to be extra careful. Because there are an infinite number of these things, we cannot add them to
     the list of known-key names used to initialise the original name cache. Instead, we have to rely on
     never having to look them up in that cache.

     This is accomplished through a variety of mechanisms:

       a) The known infinite families of names are specially serialised by BinIface.putName, with that special treatment
          detected when we read back to ensure that we get back to the correct uniques.

       b) Most of the infinite families cannot occur in source code, so mechanism a) sufficies to ensure that they
          always have the right Unique. In particular, implicit param TyCon names, constraint tuples and Any TyCons
          cannot be mentioned by the user.

       c) Tuple TyCon/DataCon names have a special hack (isTupleOcc_maybe) that is used by the original name cache
          lookup routine to detect tuple names and give them the right Unique. You might think that this is unnecessary
          because tuple TyCon/DataCons are parsed as Exact RdrNames and *don't* appear as original names in interface files
          (because serialization gives them special treatment), so we will never look them up in the original name cache.

          However, there is a subtle reason why this is not the case: if you use setRdrNameSpace on an Exact RdrName
          it may be turned into an Orig RdrName. So if the original name was an Exact tuple Name we might end up with
          an Orig instead, which *will* lead to an original name cache query.

This section tells what the compiler knows about the association of
names with uniques.  These ones are the *non* wired-in ones.  The
wired in ones are defined in TysWiredIn etc.

The names for DPH can come from one of multiple backend packages. At the point where
'basicKnownKeyNames' is used, we don't know which backend it will be.  Hence, we list
the names for multiple backends.  That works out fine, although they use the same uniques,
as we are guaranteed to only load one backend; hence, only one of the different names
sharing a unique will be used.

Certain class operations from Prelude classes.  They get their own
uniques so we can look them up easily when we want to conjure them up
during type checking.

NOTE: @Eq@ and @Text@ do need to appear in @standardClasses@
even though every numeric class has these two as a superclass,
because the list of ambiguous dictionaries hasn't been simplified.

\begin{code}

-- The "standard classes" are used in defaulting (Haskell 98 report 4.3.4),
-- and are: "classes defined in the Prelude or a standard library"
