Brief

Ryan L. Peterman’s tweet relays an interview quote that frames a trade-off between C and Haskell: C yields quick performance at the cost of long correctness work, while Haskell yields quick correctness at the cost of potential long optimization. Peterman labels it “interesting” and intends to share the interview.

Why it matters

Ryan L. Peterman posted a quote contrasting C and Haskell: “In C, you will spend one week to make it efficient, and then you will spend one year to make it correct; In Haskell, you spend one week to make it correct, and then you may spend one year to make it efficient.”
