It depends on Stream, which specifically may become a liability

[1 of 1] Compiling Data.Stream      ( Data/Stream.hs, dist/build/Data/Stream.o, dist/build/Data/Stream.dyn_o )
Data/Stream.hs:105:3: warning: [GHC-22705] [-Wnoncanonical-monad-instances]
    Noncanonical ‘return’ definition detected
    in the instance declaration for ‘Monad Stream’.
    ‘return’ will eventually be removed in favour of ‘pure’
    Suggested fix:
      Either remove definition for ‘return’ (recommended) or define as ‘return = pure’
