So, I've read that one should avoid monadic generators in general due to reducing the effectiveness of shrinking. Does this imply that using
```haskell
{-# LANGUAGE ApplicativeDo #-}

`Data.Graph.Inductive.Internal.Queue` isn't efficient for persistent use. It would be easier to ensure that it's not accidentally used persistently if it's given a monadic interface. It should probabl…

I am running into an issue with monadic parsers and error correction.
Take for example this parser that parses natural numbers, but only if their value is below `42`:
```Haskell

In monadic code, the functions build computations which are returned and then executed. Once we're actually inside the monad executing code, the original function names are long gone. We need a sche…

I think these probably deserve to exist. Here's how it goes for Moore machines (I didn't try to figure out a `Monad` instance since even if it exists it seems unlikely to be that useful):

Hi,
So, I'm trying to validate a form on my application with digestive functors but I can't find a good way to successfully do that.
I've read #236 but I can't find `FromFormUrlEncoded` class. W…
