[Haskell-cafe] I read somewhere that for 90% of a wide class of computing problems, you only need 10% of the source code in Haskell, that you would in an imperative language.

You word the (hypothetical) question with a bias toward imperative

Why isn't the question "What is the sum of a list of numbers?", which is
biased toward the declarative?
