[Haskell-cafe] Re: Need some help with an infinite list

Hi Tom, thanks for that. I remembered reading about that in my earliest haskell days, couldn't find it again and couldn't get it right by myself either. Günther Tom Pledger schrieb:

Hi guys,

I'd like to generate an infinite list, like

["a", "b", "c" .. "z", "aa", "ab", "ac" .. "az", "ba", "bb", "bc" .. "bz", "ca" ...]

If you're happy to have a "" before the "a", you can do this as a fairly cute one-liner in a similar style to this list of Fibonacci numbers.

fib = 0:1:[m + n | (m, n) <- zip fib (tail fib)]

Regards, Tom
