That is true for only the simplest of code - and untrue for anyone who has a library that defines a Monad - or anyone who has a library that they want to keep "up to date". Do you really want to have a library where all your "how to use this" code has return in the examples? Shouldn't now be pure? Do I now need -XCPP just for Haddock? and my wiki page? And what gets shown in Hackage? This is just a nightmare for a huge number of libraries, and especially many commonly used ones.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Why bother!</div><div class="gmail_extra"><br></div></div>
