# By default, DalliStore doesn't deal with `raw` correctly when inside the
# LocalCache per-request middleware. The MemCacheClient fixes this already by
# adding another little module. Let's do the same.
#
# A PR has been lodged upstream:
#
# https://github.com/mperham/dalli/pull/481
#
# Once merged @sj26 will update dalli and remove this workaround.
