Hi Yasuyuki,
Here is some resource Brent produced, why tail-recursion isn't that
important in haskell:
http://www.haskell.org/pipermail/haskell-cafe/2009-March/058607.html
(http://www.haskell.org/haskellwiki/Tail_recursion)
I think it is nice to have some background (and it is pretty interesting).
Greets,
Edgar

Hi Brent,

However, the real answer is: don't worry about it! Because of Haskell's lazy evaluation, the notion of "tail call" is not very important. And even if it were, you still shouldn't worry about it: just write your Haskell programs in the most natural, beautiful style you can think of. Maybe at some point down the road you will have to start worrying about optimization. But you should put it off as long as possible.
Thank you for your helpful advice. In fact, I was wondering how coding styles affect optimization! I'll forget it a while.
