Python-Haskell bridge

This is indeed interesting for those (like me) wanting to introduce Haskell stealthily into a Python-based facility: essentially, leave the IO monad in Python but invoke non-IO Haskell functions.
Yes, exactly. The Haskell risk is mitigated, and you can use it exactly as you wish, for strongly typed, purely functionaly, robust components held together with Python glue. And then its easier to sneak Haskell into an existing python toolchain.
Benefits for Haskell
you forget about ability to use Python as scripting language inside Haskell programs. look at HsLua library as example of this
This is much less interesting for those (like me) who, once in Haskell, don't feel the least inclined to go back to Python. Missing libraries in Haskell (for my applications) are usually also missing in Python and need FFI to some (usually numeric) library written in C/C++ anyway. Why do data marshalling twice?
Agreed. There are some libraries we don't have (pygments is one). -- Don
