safeIxScruts :: Int -> [a] -> Maybe Int #
symbolExpr :: Type -> Symbol -> SM CoreExpr #
initExprMem :: SSEnv -> ExprMemory #
Initializes ExprMemory structure.
1. Transforms refinement types to conventional (Haskell) types.
2. All Depths are initialized to 0.
insEMem0 :: SSEnv -> SM ExprMemory #
applyTy :: [Type] -> CoreExpr -> Maybe CoreExpr #
Used for instantiation: Applies types to an expression.
> The result does not have forall.
Nothing as a result suggests that there are more types than foralls in the expression.
instantiateTL :: SM (Type, CoreExpr) #
Instantiate the top-level variable.
apply :: [Var] -> CoreExpr -> Maybe CoreExpr #
Applies type variables (1st argument) to an expression.
The expression is guaranteed to have the same level of
parametricity (same number of forall) as the length of the 1st argument.
> The result has zero forall.
