That's a separate issue. It is indeed what OverloadedStrings is for. Perhaps we can have a new ticket for it. But we can't talk meaningfully about it until we settle the first issue: what are the primitive types and operations over them. There I think we have a preliminary consensus, with B# = ByteArray#.
My intention is to add a way to let user choose which primitive types he/she wants. But if there's a must to fix a primitive type, `ByteArray#` may be better than `Addr#` since it can be cast into `Addr#` not vice- versa(at the cost of extra info-header and length words). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5218#comment:94 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
