I think this is exciting and has a valid use case. The other day we were explaining Python list comprehensions which was heavily inspired by Haskell's list comprehensions. But it was no where as concise or expressive as Haskell. In many cases Haskell is very concise and it helps to have an option on the interactive interpreter to enter a Haskell one-liner to prototype a solution.
