Wolfgang and Remi,
Thanks to you both for the explanation. Yes, the GHC Integer type does what I was referring to and clearly anything done at runtime will slow execution.
For future reference, if I know an integer will never exceed an Int, I should type it that way to optimize speed; but using Integer will optimize safety - right?
Right. If performance is not such a big concern it would also be appropriate to always use Integer. Then you would always be on the safe side.
