List.partition a bit too eager

[Simon Peyton-Jones]

It's a bug in the defn of 'partition' in the Haskell 98 report.
I have (still) failed to publish this as an errata, let alone revise
the report itself, so the buggy defn stands at present, I'm afraid.

I really plan to get to the revision in early '01.

| I think the following program
| 
| import List
| main = putStr . show . fst . (partition id) . cycle $ [True,False]
| 
| should display [True,True,True,...].  But instead, for both 
| GHC and Hugs,
| you get a stack overflow.  Is this a bug, or could someone 
| explain it to me?
