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

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? -- Ariel J. Birnbaum
