getRewrite :: OCAlgebra oc Expr IO -> RewriteArgs -> oc -> SubExpr -> AutoRewrite -> MaybeT IO ((Expr, Expr), Expr, oc)

Yields the result of rewriting an expression with an autorewrite equation.

Yields nothing if:

• The result of the rewrite is identical to the original expression
• Any of the arguments of the autorewrite has a refinement type which is not satisfied in the current context.

subExprs :: Expr -> [SubExpr]

unify :: [Symbol] -> Expr -> Expr -> Maybe Subst

unify vs template e = Just su yields a substitution su such that subst su template == e

Moreover, su is constraint to only substitute variables in vs.

Yields Nothing if no substitution exists.
