Provide a way to retag S3Configuration values

[ocharles]

S3Configuration carries a phantom type of the request type. I am storing my S3Configuration in a bigger Env data type, and it's fine if I always do NormalQuerys. However, I need to do both types of queries, so I end up having to do:

    let s3' = case s3 of
                S3.S3Configuration a b c d e f -> S3.S3Configuration a b c d e f

It would be nice if aws provided this inside the library itself.

Can't you use a polymorphic S3Configuration?

[ocharles]

My use case at the time was to store the S3Configuration in some other piece of data, so to make it polymorphic meant I would have to introduce a new type parameter for that data type - which I would prefer to avoid. I don't think it's possible to do it with a forall either, because when I create an S3Configuration I am choosing a concrete instantiation of the type parameter.

Hi ocharles,

Tried a newtype wrapper?

Cheers,
