...ns, by running with +RTS -p -hy, which creates A.hp, which you can view by converting it to a postscript file (hp2ps -c A.hp), generating:
which tells us there's nothing wrong with your memory use: it is allocating in constant space.
So your problem is algorithmic complexity of numDivs:

When is memoization automatic in GHC Haskell?
... little tricky when you use syntactic sugar like in your example, so let's convert these to equivalent desugared syntax:
m1' = (!!) (filter odd [1..]) -- NB: See below!

(Note: The Haskell 98 report actually describes a left operator section li...
Memoization in Haskell?

Since we can index, you can just convert a tree into a list:
toList :: Tree a -> [a]
toList as = map (index as) [0..]
You can check the work so far by verifying that toList nats gives you [0..]
Now,
f_tree :: Tree Int
f_tree = fmap (f fastest_f) nat...
When should I use RequestFactory vs GWT-RPC?

On the client you need to convert "PROXIES" to your client domain objects and vice-versa. This is completely ridiculous. It could be done in few lines of code declaratively, but there's NO SUPPORT FOR THAT! If only we could map our domain objects to p...
