Yes, if you do not use high-level concepts and optimize everything by
hand, it requires a lot of testing. :)

I am not aware of such a library, but IMHO this code will be very simple.

Write an isomorphism between @BitList b@ and @ListStep (BitList b)@

Hello.
IMHO there are 2 ways to define categories in Haskell:
W0) the category of types and functions ("base.Data.Functor" and company
belongs to it);
W1) the class "base.Control.Category.Category".
(Defining a category where the class of objects is a type seems
impossible in Haskell.)

but there are further limitations on the arguments, and worse, the function
doesn't check this and produce an error if the arguments don't conform,
but just silently produces a meaningless result.
How can 'deleteBy' check that an argument is an equivalence relation?
s are in a miserable state of not respecting docs
when the docs are complete.
Why should anyone expect

You can store a set of rules in IORef or another IO-mutable type. I

transformFirst f (x, y) = (f x, y)
maybe f = transformFirst (\g x -> g x >>= f)

filter f = maybe (\x -> if f x then Just x else Nothing)
