# Memoize module simply memoizes the values returned by lookup using
# a flat hash and can tremendously speed up the lookup process in a backend.
#
# To enable it you can simply include the Memoize module to your backend:
#
# I18n::Backend::Simple.include(I18n::Backend::Memoize)
#
# Notice that it's the responsibility of the backend to define whenever the
# cache should be cleaned.
