Re: [Haskell-beginners] Query regarding an unusually behaving code

      Gah, got here late and missed that this was a response, not the problem
description. That's twice now I've put my foot in it. Stupid mailinglists,
with no edit buttons...

Well at least in both cases I've added SOMETHING useful. :)

GHCi doesn't quite support everything you could put in a source file. To
do what you want here, you need to use Haskell's alternative block syntax:
:{
let { digs 0 = [0]
    ; digs x = (digs (x `div` 10)) ++ [(x `rem` 10)]
    }
:}
...yep, curly braces and semicolons just like C-family. :) It's intended
for machine-generated code, but works for this too. And in fact you
actually don't need multi-line, this is legal:
let { digs 0 = [0]; digs x = (digs (x `div` 10)) ++ [(x `rem` 10)] }

In ghci you want to make a multi-line expression:
:{
let digs 0 =[0]
    digs x = (digs (x `div` 10)) ++ [(x `rem` 10)]
:}
(Note we don't put "let" on the second line)
