Probably if the take function were being designed today, there would be no question about whether it should take Int or Integer. Back then, the Integer overhead was high enough to worry about, and lots of benchmark programs used take/drop. Nowadays, we can't really change the type of take without breaking just about every Haskell program.
Ok, but the whole library hierarchy is pretty new, right? There is no reason for Data.FiniteMap.sizeFM to be Int. Moreover take and drop in Data.List could be redefined to take Integer without breakage etc.
It is likely that Data.FiniteMap will be replaced soon anyway. See recent discussions on libraries@haskell.org. Cheers, Simon
