The target audience is non-Haskell programmers, and if you don't think the tutorial is good enough to onboard such a programmer then I consider that a bug against the library. I would actually appreciate if people submitted Github issues highlighting any pedagogical problem with the tutorial.

I think the use of `liftIO` is a reasonable objection. When I wrote the library I had the choice of utomatically pre-wrapping all `IO` commands with `liftIO` for the user (making them all `Shell` commands) by default. However, I decided not to do that for two reasons:

* If you do that you can't use them outside of a `Shell` any longer * The user has to learn `liftIO` anyway if they want to use `IO` actions not provided by the `turtle` library. I didn't want to teach the user a leaky abstraction

I don't see any issue with `do` notation is bad. Same thing with parser combinators, which are just strings in the simple case, and the "Patterns" section of tutorial has a table showing you how to convert regular expression idioms to `Pattern`s:

http://hackage.haskell.org/package/turtle-1.0.0/docs/Turtle-...

The language pragma is sort of a grey area. I decided to keep it because it doesn't take a long time to explain and it significantly increases the usability of the library.

I think you mentioned at some point the goal is to get folks using large python scripts to use this instead. I would be very curious to hear how that progresses.
