Is there any way in which I can do without IORef in tabHandler and commandLoop (written in red and bold, if you can see)?
You could just always redefine the key binding for \t with a new closure which contains the updated "pwd" value (or the whole state if you like it more that way). I suppose readline supports key binding redefinition (???). But I do not think I like it more that IORef, I rather use IORefs with imperative interfaces :-) Peter.
