As this is not a common ask, probably not, but we are open source and take contributions! Take a look at our F# support. This should be a relatively easy integration, you'd just need to pass the code to a command line for Haskell.

It might even be possible to do this with a Batch script today. Just upload the Haskell binary, and have it load a particular file in your functions directory. There's are some Batch templates you can get started with.
