UUID serialization incorrect #35
Description
arg->str protocol method for ArgumentFormatter serializes a UUID as a string, not a string of a string.
e.g., expect #uuid"baf4cce4-da42-4dc2-aea6-ab1e8d63196c" to serialize as "\"baf4cce4-da42-4dc2-aea6-ab1e8d63196c\"", instead get "baf4cce4-da42-4dc2-aea6-ab1e8d63196c".
ArgumentFormatter needs to be extended to UUID.
