Since Haskell can infer types most of the time, try
foo 0 = []
foo x = ['1'] ++ foo(x - 1)
with this loaded into hugs you can then try

Well, it *is* too general. :)

Well, the bits are frozen, but I propose to regard this as a gross

this case, a set of characters).

Hi Folks,
I've put up a binary dist for sparc-sun-solaris2 at
http://research.microsoft.com/users/t-simonm/ghc/dist/working/ghc-pre-4.03-s
parc-sun-solaris2.tar.gz
This is built from our current sources (i.e. 4.02 + patches). Have fun!
Simon
