Then, I immediately blow my stack if I try something like:

The culprit is actually sum which is defined in the base libraries
as either a foldl or a direct recursion depending on a compiler
flag. In either case, the code is not strict enough; just trying to
compute:
sum [1..10000000]
There's also an insufficient-laziness issue with enumerations in at
least some versions of the standard library, IIRC. meaning that just
saying [1..10000000] can introduce a space leak that can lead to a
stack blowout.
