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. `AnnKeywordId`s `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

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.

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. `AnnKeywordId` : `AnnDcolon`, `AnnComma`
PatSynSig [Located (IdP pass)] (LHsSigType pass)	A pattern synonym type signature pattern Single :: () => (Show a) => a -> [a] `AnnKeywordId` : `AnnPattern`, `AnnDcolon`,`AnnForall` `AnnDot`,`AnnDarrow`
ClassOpSig Bool [Located (IdP pass)] (LHsSigType pass)	A signature for a class method False: ordinary class-method signature True: generic-default class method signature e.g. class C a where op :: a -> a -- Ordinary default op :: Eq a => a -> a -- Generic default No wildcards allowed here `AnnKeywordId` : `AnnDefault`, `AnnDcolon`
IdSig Id	A type signature in generated code, notably the code generated for record selectors. We simply record the desired Id itself, replete with its name, type and IdDetails. Otherwise it's just like a type signature: there should be an accompanying binding
FixSig (FixitySig pass)	An ordinary fixity declaration infixl 8 *** `AnnKeywordId` : `AnnInfix`, `AnnVal`
InlineSig (Located (IdP pass)) InlinePragma	An inline pragma {#- INLINE f #-} `AnnKeywordId` : `AnnOpen` `'{-# INLINE'` and `'['`, `AnnClose`,`AnnOpen`, `AnnVal`,`AnnTilde`, `AnnClose`
SpecSig (Located (IdP pass)) [LHsSigType pass] InlinePragma	A specialisation pragma {-# SPECIALISE f :: Int -> Int #-} `AnnKeywordId` : `AnnOpen`, `AnnOpen` `'{-# SPECIALISE'` and `'['`, `AnnTilde`, `AnnVal`, `AnnClose` `']'` and `'#-}'`, `AnnDcolon`
SpecInstSig SourceText (LHsSigType pass)	A specialisation pragma for instance declarations only {-# SPECIALISE instance Eq [Int] #-} (Class tys); should be a specialisation of the current instance declaration `AnnKeywordId` : `AnnOpen`, `AnnInstance`,`AnnClose`
MinimalSig SourceText (LBooleanFormula (Located (IdP pass)))	A minimal complete definition pragma {-# MINIMAL a \| (b, c \| (d \| e)) #-} `AnnKeywordId` : `AnnOpen`, `AnnVbar`,`AnnComma`, `AnnClose`
SCCFunSig SourceText (Located (IdP pass)) (Maybe (Located StringLiteral))	A "set cost centre" pragma for declarations {-# SCC funName #-} or {-# SCC funName "cost_centre_name" #-}
CompleteMatchSig SourceText (Located [Located (IdP pass)]) (Maybe (Located (IdP pass)))	A complete match pragma {-# COMPLETE C, D [:: T] #-} Used to inform the pattern match checker about additional complete matchings which, for example, arise from pattern synonym definitions.
