My printf was a sprintf too. I.e., the return value could be eoither `IO a' or String. Easy to implement, but probably confusing. :)
I noticed that. I don't yet fully understand how it all works, but it did strike me as very neat.
The trick Lennart is using is indeed neat. But afaIct it is not known to most Haskell hackers. It deserves better attention. Another library which uses this kind of trick is Björn Bringert's XML-RPC library: http://www.dtek.chalmers.se/~d00bring/haskell-xml-rpc/ Cheers, /Josef
