If you say so...
It is nice to be so categorical.
But not all people would dare...
Already source parsers in Haskell are not so straightforward. Monadic are
very nice. People teach compilation in such a way, (I did it myself but
I didn't care about efficiency). Swierstra et al. did a great job, but the
result is not easy to master. 

So, in general, although I am on your side concerning the usage of Haskell,
I must say that I hate the philosophy "Eine Kirche, eine Sprache"... 

If the context - as here - is often very <<stateful>>, we, the True
Functional Believers have no chance to convince people to use functional
languages, if they are used to other style of programming. That's why I
was surprised that somebody got surprised. There is no need to convince
people reading this list. Try to convince others...
