Because ByteString is optimised for dealing with big blobs of binary
data, its performance when you split a big ByteString into a pile of
words is quite poor.  Also, people use ByteStrings for dealing with text
mostly because their native character sets let them get away with it,
not because it's an intrinsically good idea.
