The warning given for HashMap.toList is missing here:

unordered-containers/Data/HashSet/Internal.hs

Lines 441 to 444 in 259dc9e

-- | \(O(n)\) Return a list of this set's elements. The list is
-- produced lazily.
toList :: HashSet a -> [a]
toList t = Exts.build (\ c z -> foldrWithKey (const . c) z (asMap t))

Note that the order of elements depends on which version of hashable this package is built against, even which minor version (which I find dubious):
