I want to announce first release of [inline-python](https://hackage.haskell.org/package/inline-python-0.1). It’s inspired by `inline-r` and allows to embed python snippets which can capture values including haskell function from outside scope. For example:

```haskell
{-# LANGUAGE QuasiQuotes #-}
import Python.Inline
import Python.Inline.QQ

main :: IO ()
main = withPython $ do
  let input = [1..10] :: [Int]
  let square :: Int -> IO Int
      square x = pure (x * x)
  print =<< runPy $ do
    fromPy' @[Int] =<< [pye| [square_hs(x) for x in input_hs] |]

```

python variables ending in `_hs` are captured from outside scope. Python’s list then converted back to haskell so program would print:

```haskell
[1,4,9,16,25,36,49,64,81,100]

```

This is alpha quality software so one shouldn’t get surprised by memory leaks, deadlocks, segfaults and things not working in general.
