FunBind | FunBind is used for both functions `f x = e` and variables `f = x -> e` 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) = ...` `AnnKeywordId`s `AnnFunId`, attached to each element of fun_matches `AnnEqual`,`AnnWhere`, `AnnOpen`,`AnnClose`,
- Fields fun_id :: Located 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 | The pattern is never a simple variable; That case is done by FunBind `AnnKeywordId` : `AnnBang`, `AnnEqual`,`AnnWhere`, `AnnOpen`,`AnnClose`,
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 | Dictionary binding and suchlike. All VarBinds are introduced by the type checker
Fields var_id :: idL var_rhs :: LHsExpr idR Located only for consistency var_inline :: Bool True = inline this binding regardless (used for implication constraints only)
AbsBinds |
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

Implicit parameter bindings.

These bindings start off as (Left "x") in the parser and stay that way until after type-checking when they are replaced with (Right d), where "d" is the name of the dictionary holding the evidence for the implicit parameter.
