In a Haskell application or a foreign one? Xmonad and lambdbabot are  
probably not bad places to start looking at methods to load new  
Haskell at runtime into a Haskell process. If you're looking at  
embedding it in a C program, http://www.haskell.org/haskellwiki/Calling_Haskell_from_C 
  is helpful, although it does require that you compile everything  
together at one time.

I've been looking into ways to load haskell code into Ruby programs at  
run-time lately, which you can check out at shimweasel.com if you like.
Briefly: dynamic library support doesn't work in ghc 6.10.1 at the  
moment, although it has at some point worked in GHC HEAD. I'm unable  
to get HEAD to build with --enable-shared on either Mac or Linux  
currently, you might have better luck.
