# The inspect_pk plugin includes the pk right next to the
# model name in inspect, allowing for easily copying and
# pasting to retrieve a copy of the object:
#
# Album.with_pk(1).inspect
# # default: #<Album @values={...}>
# # with inspect_pk: #<Album[1] @values={...}>
#
# Usage:
#
# # Make all model instances include pk in inspect output
# Sequel::Model.plugin :inspect_pk
#
# # Make Album instances include pk in inspect output
# Album.plugin :inspect_pk
