+I'm torn about this idea, if it's actually serious.  I'm very comfortable
+programming in Perl, and have written quite a few modules for IkiWiki, and
+it would be a huge pain to have to start from scratch all over again. On
+the other hand, this could be a motivation for me to learn Haskell.  My
+only encounter with Haskell has been a brief time when I was using the
+Xmonad window manager, but it looks like an interesting language.
+Functional programming is cool.
+
+There are a lot of interesting plusses for Haskell you note (in the parent
+page), but it's true that the idea is horribly daunting (as [[Joey]] said
+"If only I had a spare year").  Is there any way that you could "start
+small"?  Because nothing will ever happen if the task is too daunting to
+even start.

+On further thought... perhaps it would be easier to fork or contribute to
+an existing Haskell-based wiki, such as <a

+Rather than coding plugins for the Perl ikiwiki in Haskell, I wonder how easily a Haskell ikiwiki could still support plugins written in Perl? The (old and apparently stale) [HsPerl5](http://hackage.haskell.org/package/HsPerl5) package might provide a helpful starting point there. -- [[JoshTriplett]]
