Methods

toTTree :: a -> Reader ConversionInfo InternalTTreeSource

Instances

ConvertibleToTTree [LStmt Name] 
ConvertibleToTTree (LHsExpr Name) 
ConvertibleToTTree (HsLocalBinds Name)

HsLocalBinds is for example use for where clauses

TODO is this still needed?

ConvertibleToTTree (LHsBindLR Name Name) 
ConvertibleToTTree (HsValBindsLR Name Name) 
ConvertibleToTTree ([LPat Name], GRHSs Name, LambdaNotationStyle) 
ConvertibleToTTree (LambdaNotationStyle, LGRHS Name, Maybe (HsValBindsLR Name Name))

Constructors

FunShortNotation

may convert a where-expression to a let-expression

FunLongNotation 
Val2InlWithCase

Value bindings with guards or where expressions are replaced by a case expression case () of () |... which reflects these guards

Val2InlShort

Value bindings without guards and where expression are replaced by their left hand side surrounded by brackets.
