Re: [Haskell-cafe] better way to do this?

Excerpts from Ketil Malde's message of Wed Oct 07 05:13:19 -0400 2009:

One could argue that IO should be broken down into a set of "sub-monads" encapsulating various subsets of the functionality - file system, network access, randomness, and so on. This could extend the "safe spot" to cover much more computational real estate, and effectively sandbox programs in various ways.

You can approximate this using the Prompt monad. http://hackage.haskell.org/packages/archive/MonadPrompt/1.0.0.1/doc/html/Con... Cheers, Edward
