The set of ligatures which aligns : and </> (<:, :<, :>, >:) sadly does not include three character sequences (related #980). In Haskell, code its quite common to wrap operators between two : (starting with a : allows you to use them as a constructor). In :>: and :<: the two colons do not align, which is a bit annoying, because it breaks the symmetry.
