can we shed the names a bit? I think the operation “nubbing” should be
first, and the details (”…On”, “…By”, “…OrdOn”, “Ord”, “Int”) should be
the second component. This would also have the advantage of listing all
”nub” variants together in an index.

So:

nubOrd   :: Ord a => [a] -> [a]
nubOrdOn :: Ord b => (a -> b) -> [a] -> [b]
nubInt   :: [Int] -> [Int]
nubIntOn :: (a -> Int) -> [a] -> [a]

This is consistent with, say “map” vs. “mapM” and other suffix-based
naming in the libraries.


Greetings,
Joachim
