Thought for the day

A helpful analogy to understand the value of static typing is to look at it as putting pieces into a jigsaw puzzle. In Haskell, if a piece has the wrong shape, it simply won't fit. In a dynamically typed language, all the pieces are 1x1 squares and always fit, so you have to constantly examine the resulting picture and check (through testing) whether it's correct.
