Cond Reductions:
The following Function with conditions

max x y

| x <= y

= y

| otherwise

= x

is transformed to

max x y = max2 x y

max1 x y True = y

max1 x y False = max0 x y otherwise

max0 x y True = x

max2 x y = max1 x y (x <= y)

The following Function with conditions

undefined

| False

= undefined

is transformed to

undefined = undefined1

undefined0 True = undefined

undefined1 = undefined0 False
