Expressions proper

type LHsExpr p Source #

Arguments

= Located (HsExpr p)

May have AnnKeywordId : AnnComma when in a list

Located Haskell Expression

type PostTcExpr = HsExpr GhcTc Source #

Post-Type checking Expression

PostTcExpr is an evidence expression attached to the syntax tree by the type checker (c.f. postTcType).

type PostTcTable = [(Name, PostTcExpr)] Source #

Post-Type checking Table

We use a PostTcTable where there are a bunch of pieces of evidence, more than is convenient to keep individually.

noPostTcExpr :: PostTcExpr Source #

noPostTcTable :: PostTcTable Source #

data SyntaxExpr p Source #

Syntax Expression

SyntaxExpr is like PostTcExpr, but it's filled in a little earlier, by the renamer. It's used for rebindable syntax.

E.g. (>>=) is filled in before the renamer by the appropriate Name for (>>=), and then instantiated by the type checker with its type args etc

This should desugar to

syn_res_wrap $ syn_expr (syn_arg_wraps[0] arg0)
                        (syn_arg_wraps[1] arg1) ...

where the actual arguments come from elsewhere in the AST. This could be defined using PostRn and PostTc and such, but it's harder to get it all to work out that way. (noSyntaxExpr is hard to write, for example.)

HsVar (Located (IdP p))	Variable
HsUnboundVar UnboundVar	Unbound variable; also used for "holes" (_ or _x). Turned from HsVar to HsUnboundVar by the renamer, when it finds an out-of-scope variable or hole. Turned into HsVar by type checker, to support deferred type errors.
HsConLikeOut ConLike	After typechecker only; must be different HsVar for pretty printing
HsRecFld (AmbiguousFieldOcc p)	Variable pointing to record selector Not in use after typechecking
HsOverLabel (Maybe (IdP p)) FastString	Overloaded label (Note [Overloaded labels] in GHC.OverloadedLabels) `Just id` means `RebindableSyntax` is in use, and gives the id of the in-scope `fromLabel`. NB: Not in use after typechecking
HsIPVar HsIPName	Implicit parameter (not in use after typechecking)
HsOverLit (HsOverLit p)	Overloaded literals
HsLit (HsLit p)	Simple (non-overloaded) literals

OpApp (LHsExpr p) (LHsExpr p) (PostRn p Fixity) (LHsExpr p)	Operator applications: NB Bracketed ops such as (+) come out as Vars.

Haskell Match Context

Context of a pattern match. This is more subtle than it would seem. See Note [Varieties of pattern matches].
