I seem to be using this so often I can only attribute it to that phenomenon where after you just learned something you start seeing it everywhere.

For example:

foo = asd . evalState (do
    dsa
    sda
  )

transformed into

foo = asd .: evalState $ do
  dsa
  sda

Also consider (.) = fmap, (.:) = fmap . fmap and (.::) = fmap . fmap . fmap
