# Object can receive both last-modified in headers and last_modified in
# the body. However, originally, only last-modified was handled as an
# expected prop but it was named last_modified. Under Python 3, creating
# an Object with the body value last_modified causes the _attrs dictionary
# size to change while iterating over its values as we have an attribute
# called `last_modified` and we attempt to grow an additional attribute
# called `last-modified`, which is the "name" of `last_modified`.
# The same is true of content_type and content-type, or any prop
# attribute which would follow the same pattern.
# This example should represent the body values returned by a GET, so the keys
# must be underscores.
