I didn't know about "it" in ghci, thanks. Are there multiple levels of it?
I wanted z "a" :: Maybe Int which I understand now.
Thanks, Joel
What do you mean by multiple levels? "It" just stores the most recent expression/value. If you type "print it" then the result of the print becomes the most recent value e.g. *Foo> "boo" "boo" *Foo> :t it it :: [Char] *Foo> print it "boo" *Foo> :t it it :: () *Foo> print it () *Foo> The docs probably explain it better: http://www.haskell.org/ghc/docs/latest/html/users_guide/ch03s04.html#id31036 40 Alistair. ***************************************************************** Confidentiality Note: The information contained in this message, and any attachments, may contain confidential and/or privileged material.
