I get this point and I agree with it, but I also object to your comment on having to use transformers as otherwise it's not worthy. My objection has to do with seemingly different standards and expectations applied to levels of users of mainstream languages. In my opinion they should be the same, even if Haskell allows for safer and better results with transformers: they are not universally required and expected to be used by all haskell developers. If `unsafePerformIO` does the trick for them at the moment, so be it: they won't be worse off than Java devs.

If you aren't going to learn to write Haskell in the spirit of Haskell why learn it at all? Learning a language also involves learning the communities norms and accepted practices.
