Therefore just having

  type Method = ByteString

is also less safe, because constants for methods and i.e. header names
(if they are also just byte strings) can be mixed up without type errors.

Better would be a newtype wrapper around byte strings (or just strings):

  newtype Method = M ByteString

But I do not want to interfere with Michael Snoymann's compatibility
issues for wai.
