Re: [Haskell-cafe] Implicit newtype unwrapping

Out of curiosity, why would one want a "newtype" that were unwrapped implicitly, rather than just using "type"? Personally, whenever I use a newtype it is precisely because I *want* the compiler not to implicitly turn it into something else in order to protect myself.

So here's a totally wild idea Sjoerd and I came up with.

What if newtypes were unwrapped implicitly?

What advantages and disadvantages would it have? In what cases would this lead to ambiguous code?

Thanks,
