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.
