Whoa, seem things didn't improve since "A gentle introduction to 
Haskell".  Someone said:  "gentle as a heavy metal concert"... :D

OTOH, how can you possibly tell people about benefits of a functional 
language without mentioning recursion and tail-recursion?  How to tell 
what's so great about Haskell's type system without showing what it's 
all about?

They could just give short code examples of how to achieve practical 
stuff, but how would they explaing the code without some theoretical 
background about such issues and differences to imperative programming 
with outdated type systems?

It's not easy at all to try and write such book...
