[Haskell-cafe] Haskell Style - Pattern Matching with case vs. function declarations

[Tom.Amundsen]

Hi All,

I am new to Haskell. I just started reading "Real World Haskell" a few days
ago, so I apologize for being such a noob.

But, I am curious why I see a lot of code where people do pattern matching
via multiple function declarations instead of using the case ... of ...
construct? For example:

[code]
foldl' _    zero []     = zero
foldl' step zero (x:xs) =
      let new = step zero x
      in  new `seq` foldl' step new xs
[/code]

instead of this, which I prefer:

[code]
foldl' f acc xs = case xs of
                            [] -> acc
                            (x:xs) -> let new = f acc x
                                          in  new `seq` foldl' f new xs
[/code]
