I'm curious as well. My first thought was to try the (!!) operator. Typing

Prelude> [1..] !! 550000

overflows the stack on my computer, as does dropTest 550000.

I think its [1..] which is building up the unevaluated thunk. Using this definition of dropTest does not blow the stack: dropTest n = head . drop n $ repeat 1 Justin
