using less stack

[Amanda Clare]

I have stack problems: my program uses too much stack. I suspect, from 
removing bits of code, that it's due to a foldr in my program. If I use 
foldr or foldl on a long list (eg >500 bulky elements for a 3M stack), 
is this likely to be filling the stack? What is it that gets stored on 
the stack? If so, is there an obvious refactoring of the fold to use?
