Let's speak practically here about what kind of types we're dealing with:
* Status, including the numeric code and status message. Eg, data
Status = Status Int ByteString
* Request/response header key. In WAI, I use data CIByteString =
CIByteString !ByteString !ByteString, one version being the lowercase,
the other the original.
* Request/response header value. In WAI, I use ByteString.
* Request and response datatypes themselves. I don't think this makes
sense to put in http-types: just between WAI and http-enumerator I
needed different versions of these.
In addition to this, I think it would be convenient to have a few
extra things besides types in this package:
* Status values like we have in WAI: status200/statusOK,
* A bunch of header keys: hdrContentType, hdrAccept, etc
Ideally, this package would only rely on base and bytestring.
