Hi,

I found myself writing the following

leastFixedPoint :: (Eq a) => (a -> a) -> a -> a
leastFixedPoint f x = fst . head . dropWhile (uncurry (/=)) $ zip l (tail l)
where l = iterate f x

and was a bit surprised that I couldn't get any matches on hoogle for the type above. The closest one is fix :: (a -> a) -> a but that sort of assumes that we're starting the fixed point search from the bottom element (undefined).

Anyway, is there a nicer way of doing the above?
