[Haskell-cafe] "no-coding" functional data structures via lazyness

[Donald Bruce Stewart]

bayer:
> Learning Haskell, the Prelude.ShowS type stood out as odd, exploiting  
> the implementation of lazy evaluation to avoid explicitly writing an  
> efficient concatenable list data structure. This felt like cheating,  
> or at least like using a screwdriver as a crowbar, to be less  
> judgmental.
