Description

 

Synopsis

Documentation

tryDefault :: [TVar] -> [Goal] -> ([TVar], [Goal], Subst, [Warning]) Source

tryDefaultWith :: OrdFacts -> [TVar] -> [Goal] -> ([TVar], [Goal], Subst, [Warning]) Source

defaultExpr :: Range -> Expr -> Schema -> Maybe ([(TParam, Type)], Expr) Source

Try to pick a reasonable instantiation for an expression, with the given type. This is useful when we do evaluation at the REPL. The resaulting types should satisfy the constraints of the schema.
