Hi folks,
We have good news (nevertheless we hope) for all the lazy guys standing there. Since their birth, lazy IOs have been a great way to modularly leverage all the good things we have with *pure*, *lazy*, *Haskell* functions to the real world of files.
Maybe you know of my packages lazy-io and explicit-exception which also aim at lazy I/O and asynchronous exception handling. With lazy-io, you are able to write more complicated things than getContents. I needed this for HTTP communication that is run by demand. That is when the HTTP response header is requested, then the function could send a HTTP request first. Is it possible and sensible to combine this with safe-lazy-io? http://hackage.haskell.org/cgi-bin/hackage-scripts/package/lazyio http://hackage.haskell.org/cgi-bin/hackage-scripts/package/explicit-exceptio... I have also code that demonstrates the usage of explicit asynchronous exceptions. I have however still not a set of combinators that makes working with asynchronous exceptions as simple as working with synchronous ones: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/spreadsheet
