It seems to me that base is missing the very standard function `clamp :: Ord a => a -> a -> a -> a`:

```haskell

clamp :: Ord a => a -> a -> a -> a

clamp low high = min high .max low

```

I propose it be added to Data.Ord. It's useful, generic, and non-trivial to get right (the "big" number goes with "min" -- causes me cognitive dissonance every time.)

Thanks,

Sandy
