This back and forth on performance is great!

I often see ByteString used where Text is theoretically more
appropriate (eg. the Snap web framework) and it would be good to get
these performance issues ironed out so people feel more comfortable
using the right tool for the job based upon API rather than

Many other languages have two major formats for strings (binary and
text) and it would be great if performance improvements for ByteString
and Text allowed the same kind of convergence for Haskell.
