snowball: wrong argument order in example in haddock

[jwaldmann]

it says snowball (+) (slow 2 . rev) 8 "0 ~ . -1 . 5 3 4 . ~ -2"
https://github.com/tidalcycles/Tidal/blob/main/src/Sound/Tidal/UI.hs#L1919

but it should be snowball 8 (+) (slow 2 . rev) "0 ~ . -1 . 5 3 4 . ~ -2"
(the number of repetitions goes first).

I can send MR (but probably not today).

I wonder how bugs of this kind (code snippet in comments/documentation is out-of-synch with actual implementation) could be found automatically.

Do the examples consistently have d1 $ ... shape? then they'd be easier to detect.

Perhaps something like https://hackage.haskell.org/package/doctest-extract
