[Hugs-users] arrowp-0.5

[luc.duponcheel at accenture.com]

Hi all,

... probably a very stupid question ...

here is the content of the arrowp-0.5 README file

---begin---

Various arrow materials:

preprocessor
        a prototype preprocessor translating arrow notation to Haskell.
examples
        some illustrative applications of the preprocessor and libraries.

The preprocessor works with GHC.  The rest can be used with either Hugs
or GHC (>= 5.00).

---end---

Does this mean that the preprocessor cannot be used with Hugs?
In other words: can the generated code sometimes not be interpreted by Hugs?
(because of subtle language and/or library differences, maybe?)

I find this a little bit strange, since GHC has 'native' support for arrows
anyway (via -farrows), so why does arrowp exist if it can be used
with GHC but not with Hugs?
