By the way byteStrings are wonderful, but, it isn´t true that byteStrings are not so fast for managing short strings, for example keys ?

For short strings they're fast to use but not fast to construct and not very memory efficient. There's 20 bytes overhead per ByteString. A packed string type optimised for short strings would make different design decisions. Duncan
