Re: [Haskell-cafe] Re: Embedding newlines into a string?

Ariel, In response to your comment, since there was apparently no section devoted to pitfalls of iterating over lists, I have added the section "1.4 Iterating Over a List" in the following HaskellWiki page; viz: Common Misunderstandings - HaskellWiki http://www.haskell.org/haskellwiki/Common_Misunderstandings#Iterating_Over_a... Hope this helps.... Benjamin L. Russell --- "Benjamin L. Russell" wrote:

Ariel,

Check out the following HaskellWiki pages:

Common Misunderstandings - HaskellWiki

http://www.haskell.org/haskellwiki/Common_Misunderstandings

Things to avoid - HaskellWiki http://www.haskell.org/haskellwiki/Things_to_avoid

Hope these help....

That's exactly what I was thinking about, but your hanoi_shower only handles list of exactly one action, but you have to handle longer lists, too. This could be done with explicit recursion

This seems to be a common pitfall for Haskell newcomers: mistaking a single-element list pattern (such as [x]) for a pattern that iterates over every element in the list. I can't seem to find a page with a list of common pitfalls and mistakes... is there such a thing?
