I agree with that. The and = ... wasn't really an improvement over and 
xs = ... xs, and if the later is easier to read that's good.

Btw.:

What happened to isSpace, toLower and toUpper (, from the tutorial)? 
(I)sSpace must be there for words anyway, so I can't see why it's 
missing. (T)oLower and toUpper might have some subleties with 
internationalization and stuff, but they would be useful for me even as 
a poor man's version which can just convert "A-Z", "a-z" and no umlauts.

I feel that Haskell is missing some basic string manipuation functions, like
- replacing all occurances of one substring (or sublist) with another 
string (or list).
- tokenize a string by an arbitrary delimeter

I know many of these functions can be written in Haskell without much 
effort. But I don't really want to "invent" isSpace for any program.
