FunBind

Function-like Binding

FunBind is used for both functions f x = e and variables f = x -> e and strict variables !x = x + 1

Reason 1: Special case for type inference: see tcMonoBinds.

Reason 2: Instance decls can only have FunBinds, which is convenient. If you change this, you'll need to change e.g. rnMethodBinds

But note that the form f :: a->a = ... parses as a pattern binding, just like (f :: a -> a) = ...

Strict bindings have their strictness recorded in the SrcStrictness of their MatchContext. See Note [FunBind vs PatBind] for details about the relationship between FunBind and PatBind.

AnnKeywordIds

• AnnFunId, attached to each element of fun_matches
• AnnEqual,AnnWhere, AnnOpen,AnnClose,

Fields

• fun_id :: Located (IdP idL)
• fun_matches :: MatchGroup idR (LHsExpr idR)

  The payload

• fun_co_fn :: HsWrapper

  Coercion from the type of the MatchGroup to the type of the Id. Example:

       f :: Int -> forall a. a -> a
       f x y = y
  

  Then the MatchGroup will have type (Int -> a' -> a') (with a free type variable a'). The coercion will take a CoreExpr of this type and convert it to a CoreExpr of type Int -> forall a'. a' -> a' Notice that the coercion captures the free a'.

• bind_fvs :: PostRn idL NameSet

  After the renamer, this contains the locally-bound free variables of this defn. See Note [Bind free vars]

• fun_tick :: [Tickish Id]

  Ticks to put on the rhs, if any

PatBind

Pattern Binding

The pattern is never a simple variable; That case is done by FunBind. See Note [FunBind vs PatBind] for details about the relationship between FunBind and PatBind.

Fields

• pat_lhs :: LPat idL
• pat_rhs :: GRHSs idR (LHsExpr idR)
• pat_rhs_ty :: PostTc idR Type

  Type of the GRHSs

• bind_fvs :: PostRn idL NameSet

  After the renamer, this contains the locally-bound free variables of this defn. See Note [Bind free vars]

• pat_ticks :: ([Tickish Id], [[Tickish Id]])

  Ticks to put on the rhs, if any, and ticks to put on the bound variables.

VarBind

Variable Binding

Dictionary binding and suchlike. All VarBinds are introduced by the type checker

Fields

• var_id :: IdP idL
• var_rhs :: LHsExpr idR

  Located only for consistency

• var_inline :: Bool

  True = inline this binding regardless (used for implication constraints only)

AbsBinds

Abstraction Bindings

Fields

• abs_tvs :: [TyVar]
• abs_ev_vars :: [EvVar]

  Includes equality constraints

• abs_exports :: [ABExport idL]

  AbsBinds only gets used when idL = idR after renaming, but these need to be idL's for the collect... code in HsUtil to have the right type

• abs_ev_binds :: [TcEvBinds]

  Evidence bindings Why a list? See TcInstDcls Note [Typechecking plan for instance declarations]

• abs_binds :: LHsBinds idL

  Typechecked user bindings

• abs_sig :: Bool

TypeSig [Located (IdP pass)] (LHsSigWcType pass)

An ordinary type signature

f :: Num a => a -> a

After renaming, this list of Names contains the named and unnamed wildcards brought into scope by this signature. For a signature _ -> _a -> Bool, the renamer will give the unnamed wildcard _ a freshly generated name, e.g. _w. _w and the named wildcard _a are then both replaced with fresh meta vars in the type. Their names are stored in the type signature that brought them into scope, in this third field to be more specific.
