Many useful programs that I would like to write in Haskell don't fall into this category -- for example, network servers -- but a lot of their components do. Can these components can be Haskell functions without IO in their signatures?
I'm working on a report generator (for my own use, probably will be too limited for practical use until/unless I have a need); the input data and output ultimately have to be in IO, but the bulk of the program (and all of the library) is pure; you *want* a report to produce the same output for the same input. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
