class Cache
# The {Temporary} cache is intended for a single request, script,
# migration, etc. It allows you to alter a card and then retrieve
# the card with those alterations intact _without_ saving those
# changes to the database.
#
# In practice, it's a set of Cache-like methods for using a
# simple Hash.
#
# Unlike the Persistent cache, the Temporary cache can handle objects with
# singleton classes.
