I liked the original idea. I'm not sure if I agree with the argument that allowing fully-fledged IO actions in the initialisation of a module is unsafe. I agree that it is a little opaque, in the sense that one can't easily tell whether a particular init action is going to run or not. On the other hand, instances currently have the same "problem": you can't tell what instances are in scope in your module without looking through the transitive closure of modules you import, including libraries, which you might not have source code for. The proposed scheme wouldn't allow forcing an ordering on init actions between two modules (eg. initialise the network library, then initialise the HTTP library). In any case, we're not going to rush to implement anything. Discuss it some more ;-) Cheers, Simon _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
