Comment (by shelbymoore3):
The suggested iterate function remains as stated. I just want to point
out my example lamba function usage was not returning a list. Corrected:
fibs = iterate (\x -> [last x + last init x]) [ 0 : 1 ] where
Ditto (and I think I need to add the semicolon in the one line guard?):
fibs = iterate (\x -> [fib -1 + fib -2] where fib i = | i==-1=last x; |
i==-2=last init x) [ 0 : 1 ]
