Hi all, In chapter 4 in Real World Haskell comes there the first example of system I/O, namely `interactWith`. According to author, the right way is to compile and run program in system shell, though I have loaded source in GHCi and can't figure out how to invoke `main` interactively. Therefore the question is simply how can I call `main` that takes arguments in GHCi? Thanks. BTW: This is my first message to the group and if there is any restriction I violate in topics, I'd like to know. The example I mentioned can be found at the beginning of the web page followed by link http://book.realworldhaskell.org/read/functional-programming.html -- Best Regards Yang Zhao
