Hello Justin,

I tried and what I saw was a constant increase in memory usage. Any particular profiling option that you would use?

A great place to get started with profiling is the chapter in Real-World Haskell: http://book.realworldhaskell.org/read/profiling-and-optimization.html For a problem like this I would look at general heap profiling (-hc), retainer profiling (-hr), and also type profiling (-hy) to see if any of them provide new insight. For example, -hc might tell you which functions are problematic, but -hr is more likely to help you there. Sometimes the specific type that is leaking is not what you think and that's why -hy is nice. I hope that helps, Jason
