You want to make sure you set up the appropriate code before loading the
static_cache plugin, as after you load it, it may be too late. However,
starting with Sequel 5.12, you can call load_cache after loading the plugin
to repopulate the cache, so you could load the plugin, make your changes,
then call load_cache afterward.
The standard way to have caching work for frozen objects is to cache before
freezing, so you may want to try that as well (again before loading the
static cache plugin or calling load_cache):
def freeze
r18n
super
end
