It would work in the sense that it would not throw an exception, but it wouldn't work the same way in every situation. Haskell's `greet "themagicalcake"` does not correspond to Python's `greet('themagicalcake')`, nor does it correspond to Python's `lambda: greet('themagicalcake')` in every situation. E.g. you can write

  main = greet "themagicalcake"

in Haskell to get a program that just prints

  Hello themagicalcake

but the Python program

  if __name__ == "__main__":
    lambda: repeat3(greet('themagicalcake'))

prints nothing.
