Define principles for when and where we mirror and diverge from Haskell

There are times decisions made in PS have been answered with "That's how they did it in Haskell, so we'll do that here, too." I think that's a good argument because Haskell got a lot of things right. However, I think it got some things wrong. Should we clarify when we will follow Haskell and when we will diverge?

I think that PureScript is at a stage where "that's how Haskell does it" cannot be a justification for anything on it's own. My observation is that most Haskellisms come from early library development, where it was more important to have quantity vs "quality". I don't mean to say anything is low quality, just that it's significantly less cognitive weight to crib an existing interface rather than bikeshed. Unfortunately, I think that left us with a lot of paper cut inconsistencies (null vs isEmpty, void, etc).
