Description

Abstract Haskell syntax for expressions.

Synopsis

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.

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.

HsRecFld (AmbiguousFieldOcc p)

Variable pointing to record selector Not in use after typechecking

HsOverLabel (Maybe (IdP p)) FastString
