I find it impossible to get anything bang on the first time around. I find that even the best plans and ideas can start to show problems once you get into the guts of the implementation. Being able to input and edit things quickly greatly reduces the friction involved in doing refactorings. If I can do it fast enough, why not just refactor 3 different ways and see which one makes the most sense? Also helps with prototyping, being able to from a conversation to a "did you mean like this?" in 30 mins is helpful.
