I'm thinking of porting my OfflineIMAP program from Python to Haskell. In the configuration file for OfflineIMAP, I permit people to use a Python lambda expression for some things. For instance: folderfilter = lambda foldername: not re.search('(^Trash$|Del)', foldername) So I think it would be useful to be able to do something similar in Haskell. hs-plugins immediately occured to me. But there are several problems with it: 1. Only works with GHC (no Hugs) 2. Only as portable as ghci. So quite a few platforms that are important to me would be excluded (Alpha, ARM, AIX, etc.) I'm wondering if there are any alternatives? Can a Haskell program using Hugs call Hugs to evaluate an arbitrary hunk of code? Is there any portable Haskell interpreter written in Haskell? Thanks, -- John
