The type of `deleteBy` in `Data.List` could easily be generalised in a useful way.
``` deleteBy :: (a -> a -> Bool) -> a -> [a] -> [a] ```
I do not see why deleteBy should have an argument for the deleted element, anyway, since it is not even the element to delete (only an equivalent one). Wouldn't a function with type newDeleteBy :: (a -> Bool) -> [a] -> [a] be much more straight-forward?
